New description: [New technical field] This creation is related to a kind of photography monitoring device, especially a monitoring device with infrared line-type laser light source. [Prior Art] In order to continuously monitor in places where nighttime or poor lighting, the general safety monitor mostly uses an infrared light-emitting diode as a light source. However, since the light emitted by the light-emitting diode is scattered light, the distance is only exceeded. At 40 meters, the captured image will be unclear. If you encounter smoke, you should strengthen its intensity so that light can pass through the smoke. It is easy to cause the image to be unclear and too close to the exposure, resulting in the disadvantage of poor monitoring quality. Therefore, it is not conducive to the use of long-distance safety monitoring, such as coastal defense, borders or prisons. Therefore, a conventional safety monitor using an infrared illuminating diode as a light source has problems in that the far-end image is unclear and the camera has poor heat dissipation. Moreover, conventional laser long-distance light source systems utilize solid-state, gaseous or edge-emitting semiconductor lasers, which are costly to manufacture and consume a lot of power, which is not conducive to mass production. [New content] In order to solve the above problems, one of the objects of the present invention is to provide an infrared radiation type laser monitor by using a surface-emitting laser element as an infrared light source. One of the purposes of the present invention is to provide an infrared radiation type laser monitor that obtains an infrared light source that can be projected far away from a long distance by a surface-emitting laser element to achieve a clear monitoring effect at a long distance. 3 The purpose of the face-to-face is to provide a kind of (4) (four) optical module, use two:::= external light source has low light consumption, reduce power molding, two L to two, the above-mentioned object creation, an infrared radiation. ^^^^ Photographing machine main body, which includes an upper opening and a lower opening between a receiving space and a turn; - an image sensor, a system; a second: an inner opening toward the inner side; - an infrared light source module In the Dugu corpse, where the infrared light source module is used - the surface-emitting laser: and the plurality of laser wafers are arranged facing the upper opening direction; and an optical =: the second system is disposed and covers the upper opening The optical lens module has a light-transmitting region of the H-shirt sensor and a lens region corresponding to the infrared light source module for uniformly emitting light emitted by the plurality of laser wafers. The following is a detailed description of the specific embodiments and the accompanying drawings, and it is easier to understand the purpose, skill, features and functions of the present invention. [Embodiment] In detail (4), as in T, the description of the preferred embodiment is merely illustrative of the present invention. An exploded view of the infrared surface-emitting laser monitor of different embodiments of the present invention is shown in Fig. 1, 2, and 3. 2 and FIG. 3 are not intended to show the relative positions of the components, and the detailed structure of each component is not shown. In this creation, the surface-emitting laser element is a Vertical-Cavity Surface-Emitting Laser VCSEL. FIG. 1 shows an infrared surface-emitting laser monitoring according to an embodiment of the present invention. As shown in FIG. 1 , an infrared surface-emitting laser monitor includes at least a camera body 10 , an image sensor 20 , an infrared light source module 30 , and an optical lens module 40 . The camera body 10 includes an upper opening 14 and a lower opening 16 of the accommodating space 12 and the corresponding accommodating space 12. The image sensor 20 is disposed in the accommodating space 12 and the image sensor 20 is oriented toward the upper opening 14 of the camera body 10. The infrared light source module 30 is disposed in the accommodating space 12. In the present creation, the infrared light source module 30 uses a one-shot laser element. The surface-emitting laser element includes a plurality of laser wafers 32. Among them, the laser chip 32 is disposed facing the opening 14 of the camera body 10. In the present invention, the surface-emitting laser component can be a single-element package module, such as a surface mount type (SMD type) package or a direct type (lamp type) package. In one embodiment, the laser of the inventive surface-emitting laser element has a laser wavelength of about 840 nm to 860 nm. Following the above description, the optical lens module 40 is disposed and covers the upper opening 14 of the camera body 10. The optical lens module 40 has a light transmissive area 42 corresponding to the image sensor 20 and a lens area 44 having a corresponding infrared light source module 30. The lens area 44 of the optical lens module 40 is used to uniformly emit light emitted from the laser chip 32 from within the camera body 10. Next, in an embodiment, referring to FIG. 1 , the infrared light source module 30 and the image sensor 20 are disposed on the lower opening 16 of the camera body 10 . Further, in an embodiment, the image sensor 20 is disposed along the axis of the accommodating space 12 (shown as an axis in the figure), and the plurality of laser chips 32 of the infrared light source module 30 are along the camera. The axis of the main body 10 accommodating space 12 is disposed around the image sensor 20 . Thus, the light-transmitting region 42 of the optical lens module 40 is located at the axial center of the housing space 12 of the camera body 10, and the lens region 44 of the infrared light source module 30 is disposed around the light-transmitting region 42. Referring to FIG. 1 , the infrared light source module 30 and the image sensor 20 5 M435113 are disposed on a bottom plate 50 . The material of the bottom plate 50 can be metal or a highly thermally conductive material, and the heat generated by the infrared light source module 30 and the image sensor 20 can be quickly dissipated by the material selection. It can be understood that the infrared light source module is not shown, and the image sensor can also be a separate module and then combined into a required structure. As shown in Fig. 3, in various embodiments, the bottom plate 50 (Fig. 1) can also be used as a lower cover 50' to cover the lower opening 16 of the camera body 10. As shown in Figure 2, in one embodiment, a drive member connector 60 can be disposed on the upper or lower surface of the base plate 50 (Fig. 2). The drive element connector 60 is used to drive a surface-emitting laser element. In the present invention, the light-transmitting region 42 and the lens region 44 of the optical lens module 40 are respectively disposed corresponding to the image sensor 20 and the infrared light source module 30. The optical lens structure of the lens region 44 can be a Fresnel lens, but the creation is not limited thereto. The optical lens structure of the lens region 44 can also be a plurality of lens arrays with adjustable distance and angle, or It is a single lens that can move and adjust the angle to adjust the distance between the laser beam and the surface-emitting laser element to obtain a uniform and long-range laser light. According to the above, the light emitted by the surface-emitting laser element has a collimating characteristic, and is effectively incident on the optical lens structure, thereby projecting the planar light source toward the long distance in a substantially parallel light manner, compared with the conventional light-emitting device. In terms of the use of the polar body, it has the advantages of low light consumption and reduced power cost. Furthermore, the area of the planar projection light source can be adjusted by adjusting the angle of the laser wafer or the distance from the optical lens structure. In summary, the present invention uses a surface-emitting laser element as a light source for an infrared monitor, particularly a laser-emitting element having a laser wavelength of approximately 840 nm to 860 nm. The laser element is a high directivity homology light source, has low divergence, the light beam is not easy to spread, and can maintain a very thin and straight beam, the light beam itself carries high energy, and the power consumption is small, and the projection distance is farther than the light emitting diode. The temperature is stable at 6 M435113. Therefore, the infrared monitor can be dissipated by the aluminum alloy casing, and there is no need to provide a radiator or a fan to dissipate heat, so the failure rate is extremely low and the maintenance cost is relatively low. In addition, since the infrared radiation type laser monitor of the present invention provides a high-quality infrared light source module, it can be used in a monitor to increase the shooting distance, and the laser light can penetrate even in a weather with poor weather and rain. The images taken are clearer. This creation can solve the shortcomings of current monitors using light-emitting diode light sources, such as short product life, poor night vision, high heat consumption and high cost, etc. This creation can effectively meet the trend of environmental protection and low carbon. The embodiments described above are only for explaining the technical idea and characteristics of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement them according to the scope of the patent. That is, the equivalent changes or modifications made by the people in accordance with the spirit revealed by this creation should still be covered by the scope of the patent of this creation. 7 M435113 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of an embodiment of the present invention.
