Description

Electromagnetic multibeam synchronous digital vector processing {ELECTROMAGNETIC MULTIBEAM SYNCHRONOUS DIGITAL VECTOR PROCESSING}

The present invention relates to a device for generating multibeam digital vector processing, including an optical-mechanical system such as a digital video projection engine, an electromagnetic multibeam scanning engine, optical digital transmission, wherein the system is a dynamic micro-mirror-based system. Or active or passive diffraction matrix plane-based, or may consist of disks and / or cylinders and / or rotating optical globes and / or planar or polygonal scanners that are geometrically arranged in a specific tissue.

Multibeam digital vector processing is the first of its kind in the video projection field to replace and / or complete DLP ("Digital Light Processing") technology in laser multibeam digital video projection devices intended for second generation digital cinema. Is developed.

Projections in cinemas are traditionally performed by 35mm or 70mm, or even 65mm film projectors for IMAX. DLP (: Digital Light Processing ") or LCD (" Liquid Crystal Display ") achieves an implementation based on GLV (" Grating Light Valve ") technology that allows for improved 2K x 1K resolution as well as 4K x 2K pixel resolution. A certain number of implementations based on the " liquid crystal display ") technology are now available.

Some limitations inherent in these techniques can be noted:

Using such techniques applied at higher resolutions leads to exponential costs associated with the development of the basic elements (DLP, GLV box and LCD matrix).

The use of ultra-small metal components (micro-mirrors for DLP technology, and thin micro-blades for GLVs) can result in residual magnetic fields, resonances, early aging (caused from multiple repeated torsions), oxidation, and maximum switchover. Induces a problem with the limitations concerning.

At the LCD level, the main problem is inherent in the following applications: 1) Transmittance loss and fundamental of color {red, green, blue ration, gamut, and color temperature} at the level of the recombined signal The use of dichroic filters to induce component distortion, 2) the use of LCD shutter matrices with a limited maximum activation / deactivation frequency (break cycle). These combined effects do not facilitate the process of color mixing / temperature / full range optimization with sufficient contrast level (eg 2000: 1).

It is noted that most of the limitations are due to the level of integration of the matrix technology currently used, and the present invention provides for the use of a multibeam scanning-based fourth technology that enables the generation of Ultra High Definition (UHD). . This will utilize multiple laser sources, multibeam scanning systems, and multibeam digital vector processing to achieve the formation of the image.

The use of laser scanning for projection has already been the subject of several studies. There are several primitives based on polygon or plane scanners, for example in color or monochrome. However, this technique has encountered several limitations: the availability of sources, especially blue emission sources, the availability of optoelectronic components (intensity modulators ...) compatible with resolution and refresh rate on the screen, in particular of planar scanners. Beam position control according to the change of movement speed or rotation speed of polygon scanner.

Recent advances in solid state lasers in blue and green, including data storage, enable the availability of such techniques for display and / or projection. Similarly, the rapid expansion of optical telecommunications in recent years has resulted in a new component of light intensity modulation that is fast enough to address ultra-high definition (e.g. 5000 x 3000 pixels) with a refreshed image, for example 25 times per second. Allowed for development. The conventionally required flow in non-compressed mode is about several Gbits / s.

The device developed in the present invention proposes to digitize the shape, position and trajectory as well as the image of each beam, in particular in the case of a multibeam video projector, for example in multibeam digital vector processing of the light path.

The device according to the invention makes it possible to reproduce and / or capture a sequence of colored images via a "multibeam digital video projector engine", for example by multibeam digital vector processing. This vector-type multibeam approach, for example, mixes an image with multiple spots that are patterned, overlapping or not, extended over a given area, area or volume, measured by lithography-like processes, ie in energy. Allows the creation of images or sequences of images by

Often, multibeam digital vector processing can be applied to any optical mechanical or optoelectronic device that includes an electromagnetic beam. These devices are capable of multiple transfer functions, planes and vectors, whether planar, disk-, cylindrical-, spherical-, surface-, or volume-based, active and / or passive, static and / or dynamic on a surface or in three dimensions.

Referring to the drawings, multibeam digital vector processing (FIG. 1) allows the management of devices using electromagnetic beams, which are propagated spatially and are under a certain number of reflections and / or transmissions in time. The multibeam digital vector processing device (FIG. 1) is a relative and / or absolute reference fixed by a reference point called a spatial anchor point 14 belonging to a planar or starting interface 6 in the vector chronogram 12a. In system 13 all beams are modeled by a number of N-dimensional vectors (eg, 1, 2, 3, 4, 5). The N dimension of the vector depends on the complexity and / or properties of the beam. In the case of a laser beam, for example, the vector 1 illustrating the laser is for example a coordinate (x, y, z) of the starting point, for example the space anchor point 14, for example 20, 21, It may include coordinates of direction vectors such as 22, 23, 24, and 25, information about a beam shape, information about power, information about a spectrum, and time information.

Each element, or interface (e.g., 6, 7, 8, 9, 10, 11) that makes up a device (Figure 1) using multibeam digital vector processing may be a space-time anchor in a relative and / or absolute reference system. To points (eg, 14, 15, 16, 17, 18, 19) and transfer functions. The transfer function takes into account the static and / or dynamic characteristics of the interface, and / or the coupling of electromagnetic waves with associated space-time anchor points (eg, 14, 15, 16, 17, 18, 19). The transfer function may be represented by a series of equations such as, for example, angle, Cartesian, polarity, sphere, cylinder, vector, and / or differential, and then applicable to, for example, digital signal processing, For example, whether in discrete mode, or any other digital numerical model, it may be synchronized with, for example, a Laplace function that includes a Fourier transform.

Thus, a device using multibeam digital vector processing (FIG. 1) can control the spatial, frequency, and time of the entire beam through multiple vectors (e.g. 1, 2, 3, 4, 5), and e.g. a system. It is modeled by a series of transfer functions that can be grouped together in a single transfer function that allows. The time and frequency anchor points are also associated with the space anchor points 14 to achieve more complete processing of the beam propagation.

Each transfer function, or main transfer function, is recorded or modeled in the form of a space-time chronogram 12b that allows, for example, to determine device behavior over time through a multi-frame structure. For example, planes such as 6, 7, 8, 8, 9, 10, 11 correspond to space and time cuts illustrating the progression of beam propagation from a device modeled by multibeam digital vector processing over time. do.

Here are some examples of applications of multibeam digital vector processing, and how this works:

Example 1: beam scanning through two rotating optical disks

The device of Example 1 (FIG. 2) is in accordance with a particular arrangement that allows scanning of the display area 29 by the beam 30 in accordance with vertical movement with respect to the first rotating optical disc and horizontal movement with respect to the second rotating optical disc. It consists of two rotating optical disks, for example 26 and 27, comprising a number of mirrors and / or filters and / or cavities 28. Rotation of the two rotating optical discs using the continuous beam 30 allows to determine the signature (FIG. 3) on the display area 29. In addition to spatial movement, mirrors and / or filters may be applied by spectral deformation, eg beams, eg first reflections and give (eg 32) and on second reflections (eg 33) to be provided. Filtering in the reflection of beam 30 having a spectral form (eg, 31) that can be altered by means of this can be created.

On each signature (e.g. 34 and 35), between two mirrors and / or filters (e.g. 37 and 38) that perform continuous reflection of the beam 30 between the source and the display area 29. Eclipse complications (FIG. 4) show a large number of commas (eg 36). A comma (eg 36) illustrates the projection on the plane of a possible path of the beam within the Eclipse's envelope (eg 39) signature. Eclipse phenomena modeled by multibeam digital vector processing are normalized, for example, as space-time and / or vector chronograms (FIG. 5). This chronogram identifies the spatial and temporal overlap region between the two mirrors and / or filters and / or cavities 37 and 38 and the beam 30 and thus determines the multiple paths to reach a particular point.

The first graph 40 corresponds to a position as a function of time of the disk 37, for example, and the second graph 41 corresponds to a position of the disk 38 as a function of time, for example, and the last graph 42. ) Corresponds to, for example, a combination relating to a "shoot" order. The chronogram will temporarily drive and / or modulate the incident beam according to the spatial position of the vertical rotating optical disc and / or the horizontal rotating optical disc to obtain the row 43 and / or line 44 of points.

The transfer function and configuration of the chronogram for the device using multibeam digital vector processing is numerically calculated and / or via a matrix of sensors (FIG. 7) used as an acquisition member of the resulting position of the beam over time, for example. Can be registered. The matrix 45 of sensors consists, for example, of a number of photodiodes 46 positioned according to a particular arrangement of points scanned by the beam through the device 47, for example. Order 48 allows the acquisition of each anchor point represented by sensor 46, for example. The number of anchor points for lines and rows of matrix, spatial and organizational depends on, for example, the resolution, the number of simultaneously scanned beams, the beam divergence and the like. The sensor matrix 45 is located, for example, behind two rotating optical disks 26 and 27, an elliptical electronic control 48, ie, the source 30 of the beam, and the rotating optical disks 26 and 27 and the sensor matrix 45. ) Allows for the recording of the chronogram of FIG. 5 corresponding to, for example, the moment the beam scans each photodiode, and then predicts the path of each beam according to the available shooting opportunities.

Example 2: Multibeam Scanning Engine

The device of the optical multibeam digital video projection engine (FIG. 8) is used to generate a sequence of video images, for example by lithographic construction, multibeam digital vector processing. This processing optimizes the use of the engine by mixing and / or generating an image through any scanning of the screen with any set of beams. This set of beams, eg lasers, is treated as a series of vectors passing through multiple interfaces and / or devices, eg planes, for example different at the beginning and end of each interface at space, frequency and time points. Modeled as a static or dynamic transfer function that defines beams, vectors, and coupling elements.

A possible example of an architecture for a digital video projector with optical multibeam scanning (FIG. 8) derived from an electromagnetic multibeam scanning engine and utilizing such multibeam digital vector processing includes the following features:

Multiple Optical Source Modules (49)

Optical Matricial Heads (50)

Reduction / reformatting telescope passive / static and / or active / dynamic part 51,

Optical deflection periscope (52),

Rotating optical disc 53 forcing horizontal deflection to the beam

Rotating optical disk 54 forcing vertical deflection to the beam.

The optical source module 49 is designed to achieve a collimated beam 55 from a laser diode module, for example. Depending on the configuration, such optical source module 49 may be static or dynamic.

The optical material head is a matrix 56 such as, for example, square, rectangular, circular, or any other shape, for example by means of a number of mirrors and / or filters positioned in a particular way on a pyramid, cone, plane. It is designed to achieve any pattern by structuring the beam 5 in.

The beam reduction and reformatting telescope 51 is any produced by the optical material head 50 to be small enough to impinge 50 on the digital video projection engine without being cut by the small size of the mixing element. In addition to reducing the congestion of the pattern 56, it is designed to reformat and refocus different beams, both in a static or dynamic manner, for example by passive or active components based on a lens or refractive index matrix.

The optically deflected periscope 52 is configured, for example, in a simple or complex plane, for example a plurality of areas or floors, static or dynamic. On the one hand, guide all the beams from the optical matrix head 50 to the first rotating optical disk 53 by forcing a deflection such as vertical on the beam group of the pattern 58, and on the other hand Deflection such as, for example, horizontal, into a reduced beam group of scanned reduced pattern 59 to a display area, for example a surface or a volume.

Set on rotating device 60, rotating optical disc 53 forcing vertical deflection into reduced beam group 58 may be provided with multiple mirrors and / or according to a specific arrangement allowing continuous scanning of the display area along vertical movement. Or a filter.

Set on rotating device 61, rotating optical disk 54 forcing horizontal deflection into reduced beam group 58, according to a specific arrangement allowing continuous scanning of the display area along the horizontal movement and / or Or a filter. Therefore, the device (FIG. 8) performs scanning and / or routing of the beam 58 through multiple rotating optical disks. Control integrating multibeam digital vector processing 62 allows management of the transfer function of the entire system, for example in the form of space-time chronograms and / or multi-frame synchronization.

Lithographic construction of an image is carried out with the same techniques used for printing by smart combinations of different patterns having any size and shape shared on a specific area (e.g. surface or volume), with specific mixing of the colorimetric system of each pattern Allows the eye to carry information that develops in the entire field of view and follows visual effects targeted on these areas.

Possible variant architectures of digital video projectors with optical multibeam scanning using multibeam digital vector processing include colored pixel generators. The principle of operation and all the constituent devices are the same as before (FIG. 8) except for the optical source module 49, which is replaced by colored pixel generators to introduce spectral management of the beam, eg color.

Multibeam digital vector processing (FIG. 9) models the path of multiple beams through a cross-plane, digital video projection engine (FIG. 8) through a series of vectors.

The decomposition of the multibeam scanning engine device is given in FIG. 9. The beam from the optical source module 49 is illustrated by a vector having a given size 55, for example to define the orientation, spectral characteristics, geometrical characteristics, etc. of the beam in space. The projection of this vector 55 on plane A provides for example a point 63.

The multiple optical source modules 49 extend over different crowns of the optical material head 50 and are oriented towards the central pyramid 57, for example. The optical matrix head 50 causes all the beams 55 on the same line to come from the optical source module 49. Among other things, the transfer function of the optical matrix head allows to change the spatial coordinates of all vectors 56 from the optical source module 49. The projection of this set of vectors 56 on plane B, for example, provides any matrix pattern 64, for example square. The different beams of pattern 64 then modeled by a set of collinear vectors 56 pass through the beam reformatting and reduction telescope 51. The transfer function here transforms the vector direction and / or information about the beam geometry, for example the diameter of each beam. The pattern 65 produced by the different projected beams 56 on plane C, for example, provides a reduced or “compressed” pattern 65 of the pattern on plane B, for example. This set of beams modeled by a set of collinear vectors 58 are sent to a digital video projection engine that performs multibeam scanning 59, for example projection on plane D is on plane D. Provides a pattern 66 scanned over time. The transfer function of this last device determines the orientation of each output vector 59 in accordance with the input vector 58 and the properties at a given time in the reflection and / or transmission plane of the multibeam digital video projection engine. This set of vectors is a transfer function of the multibeam video projection engine that defines the spatial, frequency and temporal characteristics of each output beam from the multibeam digital video projection engine.

Multibeam digital vector processing combines the different transfer functions, static and / or dynamic of different devices (FIG. 9) of the multibeam digital video projection engine to obtain a full transfer function that characterizes all parameters of the device. A way of managing or embedding multibeam digital vector processing is to use space-time chronograms and multi-frame synchronization.

For example, the space-time chronogram generated by recording, or by a numerical function number or non-number, is characterized by a number of anchor points 68 on the scanned area 67, a mirror of two disks from the multibeam scanning engine and And / or define images of different possible time combinations of filters and / or cavities (FIG. 10).

In order to make the image (FIG. 11) higher in density on each anchor point 68, any pattern 69 is juxtaposed along the scan through an optical material head integrated into the multibeam scanning engine.

According to an implementation variant, the optical material head 50 consists of a number of crowns, each having a number of optical source modules 49, or any spectral signature that is flexible in time, for example. Shared from the collar or electromagnetic beam generator module. Guiding the beam towards a mirror and / or filter located at the center of the ring on a support portion, such as for example pyramid 57 or cylindrical or otherwise, directs the beam to the same line and to obtain an output matrix 56. Build.

The use of multibeam digital vector processing, for example for mixing images by a multibeam digital video projection engine, performs dynamic correction of the superposition of the patterns 69, 70, 71, 72 established by the optical matrix head. Do it. Furthermore, in FIGS. 12 and 13, different patterns established by the optical material head are scanned in any manner on the projection area (eg 69, 70, 71, 72), so that part of the pattern 73 Or there is an entire overlap region. Multibeam digital vector processing applied to the multibeam digital video projection engine identifies different regions (e.g., 73 and 74) by a particular transfer function and, through interpolation or extrapolation calculations, space-time associated with the entire transfer function of the device. These overlapping regions of the pattern (e.g. 73 and 74) from optical optical heads (e.g. 69, 70, 71, 72), for example as brightness, color, shape, by alteration, static or dynamic of the chronogram Correct the spectral and frequency portions, or the resulting image, on the image.

In order to interact with the required distortion and / or correction, a number of components, static and / or dynamic, for example, complete variations of the multibeam video projection engine, such as:

Trim-correction on pyramid 57,

For example the integration of electronically controlled actuators into the optical source module 49

Active beam reformatting and reduction telescope (FIG. 14) allowing deformation of the proportional spatial and / or geometrical configuration of each beam from the optical matrix head 50 (FIG. 14).

A pyramid comprising a plurality of active mirrors and / or filters (FIG. 22),

An optical matrix head (FIG. 23 or 24), consisting of a semiconductor, with or without diffractive optical components, passive or active, that puts all output beams on the same line.

Some stability problems, or correction problems of the device may need to use a support portion with dynamic trim-correction control on the pyramid.

Depending on the implementation variant, the optical module source 49 of the optical material head 50 as a crown and / or pyramid may be switched to the matrix head as a paving of the mirror and / or filter. This structure allows to increase the density of a number of generated beams by the matrix head by frequency coding for positions in addition to the spatial coding performed by the pyramids. Each position is managed in space, frequency and time range, for example by multibeam digital vector processing loaded into the device.

According to a possible variant, the active beam reformatting and reduction telescope (FIG. 14) controlled by multibeam digital vector processing transforms the proportional spatial and geometrical configuration of each beam from the optical matrix head 50. This active beam reformatting and reduction telescope consists of, for example, a number of diffractive optical component stages (Figure 14). The first stage of the diffractive optics 75 allows for focusing and / or reducing the beams 56 one by one, for example from an optical matrix head. This first stage static or dynamic allows for individual or collective reformatting of the beam's geometry, taking into account the optical material head signature in variations of implementation. This first stage can produce a matrix of converging beams 78, for example, to reduce the diameter or to modify the shape of each beam (e.g., to make the beam circular, elliptical). For example, a second stage 76 of diffractive optics groups the beams together to collimate the beams, thereby reducing the distance between each beam 78. Finally, the last stage 77 of the example of the beam reduction telescope (FIG. 14) causes all beams 79 to be collinear at the output of component 58. Extraction (FIG. 15) is given to illustrate the operation for the beam 80 passing through the first stage 75, which is then focused 81 on the second stage 76, and finally It is oriented 82 towards the last stage 77. The development of current technologies, such as for example diffractive optics, allows for the use of dynamic components (eg 75, 76, 77) as phase space modulators, for example in beam reformatting and reduction telescopes 51. Thereafter, multiple movements in space (eg 83 and 84) are available in static and / or dynamic (FIG. 16). This then allows for example to produce fine pointing of a given area.

Thus, for example, when using a variant of multibeam digital vector processing inside a multibeam video projector, for example, the density of screen areas without correction of patterns overlapping problems (e.g., Figures 12 and 13) or omitting pixels 17 allows for dynamic correction of the form of proportional space between the beam from the optical matrix head to increase (Figs. 17 and 18).

According to a possible variant of the multibeam digital video projection engine, it is possible to achieve a pattern density densification 56 from the optical matrix head 50 by, for example, an active optical source module. The different settings of these modules include piezoelectric modules, micro, to individually modify the orientation of each beam from the optical matrix head to incorporate correction controlled by, for example, multibeam digital vector processing of a multibeam digital video projection engine. It can be done by actuator. Thus, in FIG. 17, the pattern (eg 85) may be reduced (eg 86) or enlarged 87. Depending on the configuration, the pattern produced by the optical matrix head (FIG. 18) may be square-shaped (88), or may have any shape where the beams are side by side (89) or else in case (90). have.

Example 3: Optical Digital Transmission with a Rotating Optical Disc

According to variations of implementation and use, the use of multibeam digital vector processing allows for example to drive optical digital transmission (FIG. 19) consisting of:

Multiple rotating optical discs, for example 91, 92, 93, 94, 95

Multiple delay lines, for example 96,

At the input, a number of optical material heads, for example as paving of crowns, pyramids 97 and / or mirrors and / or filters 98,

Multiple optical material heads at the output, for example as roads of crowns, pyramids 99 and / or mirrors and / or filters 100.

The optical digital transmitting device (FIG. 19) may be a rotating optical disk (eg 91, 92, 93, 94, 95), for example multi-section, single or double sided and certain mirror and / or filter elements (eg 101 ) Allows cross connection and / or routing and / or switching in an optical telecommunications network, allowing spatial and / or vector and / or angle specific addressing that depends on the following targeted effects: cross connection And / or routing and / or switching levels, joint jumps, sector jumps, section jumps, rotating optical disk jumps, insertion and / or extraction into delay line outputs, and recovery of beams at delay line outputs.

Optical material head devices (e.g. 97 and 98) are, for example, specific to ensure Gaussian beam effective propagation at the cost of spatial and / or frequency and / or temporal addressing of the payload to the right canal. It is embodied by "spatial" and "temporal" collimation through a series of reflections and / or transmissions between different virtual canals and / or pipes, coupled at an instant ("t"). Such a device is supplemented by multiple delay lines (eg 96) to reprocess the resynchronization of different signals through multiple multi-frame and multibeam digital vector processing. The number of concurrent streams with the same payload, for example 2, 3 or more, powers the device to ensure flow continuity and information integrity. The use of passive elements such as mirrors and / or filters allows for input / output reversibility (bidirectional simultaneous transmission) of the device.

As in the previous example, multibeam digital vector processing is optical in multiple planes and vectors that can be interpreted as space-time chronograms (eg 102) illustrating different interfaces or coupling planes of optical digital transmission over time. Digital transmission (Figure 19) is established. For example, on chronogram 102, plane 103 illustrates a rotating optical disk 91, plane 104 illustrates a disk 92, 105 illustrates a passage of disk 92 and , 106 and 107 illustrate the input and output of the delay line 96, 108 illustrates the passage of the disk 93, 109 illustrates the movement on the disk 93, 110 110 of the disk 94 side Illustrates the deviation, 111 illustrates the deviation toward the disk 95, 112 illustrates the passage of the disk 95, and finally 113 for the output optical material head 99 or 100. Illustrate the output of optical digital transmission. On each plane an anchor point (eg 114) on plane 113 is illustrated, which allows to track the path of the beam to optical digital transmission over time.

 For example, the first transfer function forces all parameters at spatial, frequency and temporal viewpoints in multiple beams, for example from an optical matrix head (eg 97 or 98), at the input of optical digital transmission. Each rotating optical disc (eg 91, 92, 93, 94, 95) that has its own signature is modeled by a transfer function in a common and / or relative reference system. Delay line (eg 96) resynchronizes the output signal. The transfer function mostly works on the time side.

By applying these models over a common and / or relative reference system, the transfer function series illustrates itself by space-time chronograms. Such chronograms derived from multibeam digital vector processing allow the driving of all devices of optical digital transmission, for example by multi-frame structures.

The universal transfer function of the device (eg, FIG. 19), thus identified, is built in the drive cell, for example in a field-programmable gate array (FPGA) of optical digital transmission, to achieve operation.

Due to the management in the transfer function, multibeam digital vector processing can use all calculation methods, numerical values, etc., already used, for example, in the field of signal processing.

Example 4: Optical digital transmission, for example configured as reflective and / or transmissive plane static and / or dynamic.

Depending on the availability and performance of the different possible technologies, the switching at the cross-connection, routing, space, time and frequency levels achieved by the rotating optical disk is, for example, micro-electromechanical mirrors, liquid crystals, planes and / or the like. Or may be replaced and / or supplemented by a number of devices that spatially allow beam reflection with components such as polygon scanners, diffraction and / or refractive optics, and the like.

Depending on the implementation, the arrangement of these last devices may be along one axis (FIG. 20) or several axes, for example.

Optical digital transmission (FIG. 20) is achieved for example with a plurality of micro-electromechanical mirrors and / or filter matrices (eg 115, 116, 117, 118, 119, 120), which matrices are spatially arranged and From an input level such as, for example, an optical material head such as a crown and / or pyramid 97 or a road of mirror and / or filter 98, for example crown and / or pyramid 99 or mirror and And / or deflect the incident beam towards an output level, such as an optical material head, such as the road of filter 100, at a number of specific angles, and the result of a series of reflections on the plurality of matrices has a specific orientation at a given time. .

Multibeam digital vector processing, like the previous example, distributes the device into a series of propagation vectors, planes and transfer functions, numerical values, etc. to illustrate the whole, for example in a space-time chronogram.

Electronic control allows selecting a particular addressing combination that allows cross-connection and / or routing and / or switching of the beam at its output onto an optical matrix head or the like, for example by multibeam digital vector processing.

Example 5: Matrix head for optical analysis

According to a variant of implementation and use (FIG. 21), multibeam digital vector processing allows for example to drive a matrix head, for example for optical analysis 121 consisting of the following devices:

At the input, an optical material head 122, for example a crown pyramid,

At the output, an optical material head 123, for example a crown pyramid, where the source is replaced by a sensor, for example a photodiode, and the spacing between the two optical material heads is an object or device, eg For example, to place the sample 124 to be analyzed.

The input optical material head (e.g. 122) is a different physical feature of the different beams moving between two optical material heads, for example for the geometry, velocity, and combination of the sample 124 to be tested or analyzed. A plurality of collimated collinear beams 125, for example in free space, are directed towards the other optical material head at the output 123 to allow the signature of the signal to be recovered.

This physical feature is recordable, for example, as a space-time chronogram, which exemplifies the transfer function, resulting in multibeam digital vector processing of the sample by modeling each beam as a vector.

Depending on the implementation variant for all of the above applications, multibeam digital processing can produce an optical matrix head, an active / dynamic pyramid. Moreover, miniaturization of actuators such as piezoelectrics, microjacks, for example, makes it possible to operate mirrors on the pyramids. For example a pyramid (FIG. 22) is for example stacked comprising a number of mirrors and / or filters 129, depending on the particular arrangement, by devices similar to those used for electronic components such as, for example, fin 130. It consists of as many levels as possible (eg 126, 127, 128). The level is for example linked to a control member such as a multibeam digital video projection engine driven by multibeam digital vector processing, for example on a specific electronic card 132, for example using a standard connector 132. Are stacked.

Such a dynamic pyramid device (FIG. 22) can complete beam reformatting and reduction telescope static and / or dynamic (FIG. 14), so that FIG. 17 and / or for example a multibeam digital video projection engine (FIG. 8). As shown in FIG. 8, focusing, expansion or reduction of each beam of the scanned pattern as shown in FIG. 8 is performed. All of this is driven by, for example, a control member incorporating multibeam digital vector processing (FIG. 1).

Depending on the variant of the implementation and / or depending on, for example, the targeted bulk, the optical material head used in any of the above examples may for example produce a pyramid 135 to produce an output set of collimated collimated beams. Can be achieved, for example, directly in, for example, FIGS. 23 and 24 via the semiconductor 134 crown 133 arranged in a particular manner around. Depending on the configuration, the semiconductor 134 crown 133 may include, for example, a plurality of high-brightness light emitting diodes and laser diodes, for example comprising a plurality of lenses and / or filters (eg 138 and 139). This can be accomplished by crowns (eg 136 and 137) or by optical components that allow for collimating, reorienting and filtering the beam 140 before being reflected by the central pyramid 135 (FIG. 24).

For example, deformation of a semiconductor-based optical material head such as that of FIG. 23 or FIG. 24 can be used to add, for example, a static or dynamic optical diffraction device at its output to protect the collinear and collimation of the output beam. will be. Such a device, for example linked to a control member such as a multibeam digital video projection engine, enables dynamic correction of beam position by multibeam digital vector processing. According to an implementation variant, a semiconductor-based optical material head, for example, as shown in FIG. 23 or 24, is equipped with a standard pin device 152 such as, for example, an electronic microprocessor. To link to the control member of the beam digital vector processing.

Multibeam digital vector processing makes it possible to take into account the management of different variations of optical digital transmission through chronograms and multi-frame structures, for example, in FIGS. 25 and 26. Furthermore, according to a possible variant, the optical digital transmission (FIG. 25) consists of, for example, a planar or diffraction matrix 141, for example a mirror and / or having a certain angle from the optical matrix head 97. Redirects the beam onto thin mirrors and / or filter matrix addressing through filters, micro-electromechanical mirrors and / or filters 143, 144, 145, 146 and multiple delay lines (eg, 147 and 148); And / or reformatting and / or collimating. Another possible variant of optical digital transmission (FIG. 26) consists of a plurality of dynamic diffraction matrices (eg 149, 150, 151) that allow the optical path to be dynamically generated and / or reconstructed and / or reformatted.

Different previous examples include any optical or optical machine in which multibeam digital vector processing includes planar, disk, cylindrical, spherical, surface, volumetric, active and / or passive, static and / or dynamic on a plane or in three dimensions. The device allows for example to scan shape, position, path and all electromagnetic beam characteristics. Based on a model based on the transfer function series of planes or vectors, multibeam digital vector processing allows the device to be managed using an electromagnetic beam. They propagate spatially and are under a number of specific reflections and / or transmissions in time, and each movement at the spatial and / or temporal level, for example rotational, translational, radial and / or axial circulation paths, eclipse As well as static and / or dynamic.

Thus, a device using multibeam digital vector processing may be referred to as a specific "shooting" opportunity, for example from a different time combination or from a particular addressing combination, as a space-time and vector chronogram describing a number of space-time anchor points. Is embodied. Each "shoot" opportunity is for example modeled and / or signature recording of a comma from a mirror and / or filter and / or cavity eclipse phenomenon with a particular arrangement on a rotating optical disk, for example. Multibeam digital vector processing may be implemented in an FPGA that manages the optical path for free space effective propagation of a beam, such as, for example, Gaussian through different device synchronizations.

For multi-beam devices using, for example, optical matrix heads, multi-beam digital vector processing makes it possible to achieve dynamic correction of pattern overlap, for example according to its deformation and / or correction. This may include, for example, frequency coding other than spatial coding, for example roads of mirrors and / or filters, beam reduction and reformatting telescopes, individual or collective reduction and / or reduction of beams such as optical pyramid heads as dynamic pyramids. It suggests the use of a device to enable reforming.

With this modeling of multibeam devices through vectors, planes, and transfer functions, static and / or dynamic multibeam digital vector processing can be applied to many fields such as audio-video, telecommunications, biomedical science, and the like.

As mentioned above, the invention makes it possible, for example in the case of a multibeam video projector, to digitize the shape, position and trajectory as well as the image of each beam, in particular for example multibeam digital vector processing of the optical path. Used for devices and the like.
