Description
Technical field
The present invention relates to test field of measuring technique, are related to a kind of surface of light source device for High frequency photographing measurement system.
Background technique
It is raw to be widely used in industrial or agricultural because of the advantages that its monochromaticjty is good, high directivity, high brightness for laser light source
It produces in the every field of science and technology, especially has irreplaceable work in the test measurement of China's routine war industry's weapon
With, in previous photogrammetric apparatus, mostly uses and a laser is installed beside video camera, the laser warp that laser issues
It crosses spectroscope rear portion and enters camera, be used as background light source after a part reflection.However, this there are unreasonable in structure
Property, this not only wastes energy of lasers, and the visual field of camera will receive background light source area limitation of laser light source formation etc.
Problem, and there is the phenomenon that intermediate bright surrounding dark in background light source, for photogrammetric generation strong influence.
Summary of the invention
The present invention in view of the above-mentioned problems, providing a kind of surface of light source device for High frequency photographing measurement system, shine by energy conservation
Penetrate that area is big, irradiation is uniform.
In order to solve the problems existing in the prior art, the technical scheme is that a kind of be used for High frequency photographing measurement system
Surface of light source device, it is characterised in that: including lamp box, the lamp box be all round closure hollow cavity, be provided on one side
Multiple holes are provided with uniform light board on the opposite face in the face for being provided with multiple holes on lamp box, are embedded with and expand respectively in the hole
The extension end of device, each expand device is connected by transmission fiber with laser, and the laser is with optical fiber point
The laser of light function.
The expand device is formed by expanding external structure and beam expanding lens, and beam expanding lens is fixed on the one end for expanding external structure,
The other end is equipped with port, for assigning transmission fiber.
The distance between adjacent two hole is 10-20cm on the lamp box.
The distance in the face in the face and setting uniform light board of the lamp box providing holes is 20-30cm.
The lamp box is cuboid or square.
Compared with prior art, advantages of the present invention is as follows:
The light that laser issues is expanded and is used with after even light directly as background light source by the present invention, is reduced laser and is being passed
Energy loss during broadcasting；
The laser that laser of the present invention issues uses fibre light splitting technology, and each optical fiber has certain range of exposures,
In the case where equal energy, it is possible to increase irradiated area；
Uniform light board is added in light source of the present invention, makes light source irradiation uniformly, eliminates the centre generated by laser bright week
The non-uniform phenomenon of the dark irradiation in side.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Referring to Fig. 1: the present embodiment provides a kind of surface of light source devices for High frequency photographing measurement system, including all round closure
Cuboid or square hollow cavity lamp box 1, be provided with multiple holes on one side, be embedded with expand device 3, institute in hole respectively
The expand device 3 stated is formed by expanding external structure 7 and beam expanding lens 6, and beam expanding lens 6 is fixed on the one end for expanding external structure 7, the other end
Equipped with port, for assigning transmission fiber, the structure for expanding external structure 7 is two cylinders (referring to fig. 2) for connecting into step column；
It is provided on lamp box 1 on the opposite face in the face in multiple holes and is provided with uniform light board 2, the extension end of each expand device 3
It is connected by transmission fiber 4 with laser 5, the laser 5 is the laser with optical fibre light splitting function, by laser
The laser one of sending divides more parts, is assigned into an expand device respectively.
The distance between adjacent two hole is 10-20cm on the lamp box 1；The face of 1 providing holes of lamp box and setting uniform light board 2
Face distance be 20-30cm, can making every two expand device in this way, there are certain space intervals, and the photograph in uniform light board
There is small coincidence in the face of penetrating.
Ginseng is seen figures 3 and 4, and laser forms in uniform light board a certain range of through any one expand device on lamp box
Irradiated area, and there are certain space intervals for any two expand device, and the shadow surface in uniform light board has small coincidence.
The course of work of the invention: after laser issues laser, laser carries out light splitting transmission, optical fiber through each optical fiber
The laser of transmission laser irradiation area after expand device is spread, which becomes larger, to be irradiated in uniform light board, then is formed after the even light of uniform light board
Uniform laser is irradiated, as photogrammetric required background light source.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
