Description
Technical field
This utility model is related to laser equipment field, more particularly to a kind of R-T unit for scanning laser radar.
Background technology
Fig. 1 is referred to, in existing technology, laser radar directly launches laser by laser diode, and laser is through lens
Target object back reflection is transmitted through, then is received by laser pick-off unit after lens.Due to lens to swash light transmissive effect compared with
Difficulty becomes more meticulous and standardization, laser transmission and the position that goes out possibly cannot be corresponded in laser pick-off unit, cause fraction of laser light
Do not receive so that spatial resolution is relatively low.And the difficulty of process aspect is there is also in assembling, arrangement.
Further, since the restriction in space, generally the position cloth restriction to lens and laser pick-off unit are more, it is impossible to from
By placing.
Accordingly, it would be desirable to a kind of R-T unit for scanning laser radar with new structure, can completely receive laser
Signal, obtained by scanning, resolution can also be improved.
Utility model content
In order to overcome above-mentioned technological deficiency, the purpose of this utility model to be to provide a kind of receipts for scanning laser radar
Transmitting apparatus, do not result in the loss of signal, and even off-centered signal can also be received.And laser pick-off unit and lens
Position arbitrarily can be put, and optic module will help signal transduction.
The utility model discloses a kind of R-T unit for scanning laser radar, including for sending the laser of laser
Source, changes the lens of the laser optical path that the lasing light emitter sends, and the laser is reflected back into the lens through a target object, and
A laser pick-off unit is transmitted through, an optic module between the laser pick-off unit and the lens, is additionally provided with；The optical fiber mode
Block receives the laser of the lens transmission, and the light pulse of the laser is conducted to the laser pick-off unit, wherein described
Optic module includes multifiber, and the optical fiber is arranged in array, and is integrated in an optical-fibre channel.
Preferably, width of the transverse width that the optical fiber has slightly larger than the lens.
Preferably, the laser pick-off unit is avalanche photodide.
Preferably, each optical-fibre channel and avalanche photodide communication connection described in.
After employing above-mentioned technical proposal, compared with prior art, have the advantages that：
1. densely arranged optical fiber can increase the resolution of signal reception；
2. the signal for deviateing lens centre also can be by collecting fiber so that the signal for receiving is more complete, is not in
The problem of blind area；
3. the flexible molding of optical fiber, then the placement location of lens and laser pick-off unit is freer.

Fig. 2 is the structural representation for meeting the R-T unit for being used for scanning laser radar in one preferred embodiment of this utility model
Figure；
Fig. 3 is to meet the surface chart in one preferred embodiment of this utility model after multifiber integration.
Reference：
1- lens, 2- optic modules, 3- laser pick-off units.
Specific embodiment
Advantage of the present utility model is expanded on further below in conjunction with accompanying drawing and specific embodiment.
Fig. 2 is referred to, for meeting the knot of the R-T unit for being used for scanning laser radar in one preferred embodiment of this utility model
Structure schematic diagram.In the preferred embodiment, a lasing light emitter is provided with, laser is sent out, is can be used to find range, put down, collimate,
On the laser optical path for sending, lens 1 are provided with, the laser transmission lens 1, light path change simultaneously.Laser continues to project, until one
Target object is reflected to the laser, reflection light retroeflection to lens 1, the Transflective laser again of lens 1.Laser finally by
Laser pick-off unit 3 is received, and can be found range etc. by sending and receiving phase place between laser, difference power.
An optic module 22 is provided between laser pick-off unit 3 and lens 1, and optic module 2 has a laser pick-off end, should
Laser pick-off end face, to the laser through 1 transmission of lens elder generation is connect by optic module 2 when laser directive laser pick-off unit 3
Receive.As optical fiber is in elongate shape, therefore when towards 1 laying optical fiber of lens, the number of fibers being laid with unit area can be with
A lot, that is to say, that the density of fiber deployment is much larger than the density that former laser pick-off unit 3 can be laid.Then no matter laser transmission
To where, can be received by optic module 2.Optic module 2 is connected with laser pick-off unit 3, after optic module 2 receives laser,
The light pulse of laser is conducted to laser pick-off unit 3.
Fig. 3 is referred to, and the space in order to save the optic module 2 of extra increase is occupied, many be provided with optic module 2
Optical fiber, is arranged in array, that is, stacking multifiber with a matrix type, multifiber is integrated into one by encapsulation then
In optical-fibre channel.In this embodiment, the integration of optical fiber can both protect optical fiber not damage, and be not also easy to use person and laying thoroughly
When mirror 1 and laser pick-off unit 3, need not consider whether to connect, flexible optical-fibre channel will be docked under any conditions
Mirror 1 and laser pick-off unit 3.
The characteristics of by 2 high density of optic module, high conductance, no matter laser signal off-center, light path outwards etc.,
Corresponding position arranges optic module 2 and can receive laser signal, and the laser signal " attenuating " of reception, so that improve space point
Resolution.
Width of the transverse width that optic module 2 has slightly larger than lens 1, then will not through the laser after 1 transmission of lens
Can be excessive to optic module 2, it is ensured that laser signal is all received.
In one preferred embodiment, laser pick-off unit 3 is avalanche diode (APD), and which is widely used, and is mainly used in sharp
In the reception of light, such as laser range finder, the sight of military project, and some medical apparatus and instruments etc..After there is avalanche diode, per
One optical-fibre channel is communicated to connect with an avalanche photodide, so as to receive signal.
It should be noted that embodiment of the present utility model has preferably implementation, and not this utility model is appointed
The restriction of what form, any one skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified to
Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to technical spirit pair of the present utility model
Any modification or equivalent variations and modification that above example is made, still fall within the range of technical solutions of the utility model.
