Abstract
The utility model relates to a laser light target, which belongs to the technical field of the laser light target and aims to solve the technical problem to provide the laser light target capable of reducing the influence of external light to laser signal imaging. The utility model adopts the technical scheme that the laser light target comprises a target eye, frame clips, multiple pieces of optical glass, a narrow band pass filter, an optical projection film, a white balance film and a Baader filtering film, wherein the frame clips are arranged all around the target eye, and the target eye is formed in a way that the optical glass, the narrow band pass filter, the optical projection film, the white balance film, the Baader filtering film and the optical glass are overlapped in sequence from top to bottom. The laser light target can be used for the field of optical measurement and detection.
Description
Technical field
A kind of laser light target of the utility model belongs to laser light target technology field.
Background technology
Because the laser antijamming capability is strong, resolution is higher, the error of indication is little, good stability can adapt to various bad working environment, so laser instrument becomes the optimal selection that realizes contactless telemeasurement, the laser light target is the important device that area array CCD receives laser signal, but general laser light target is easy to be subjected to the influence of ambient light, causes imaging unclear, the precision that influence is measured.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, and technical matters to be solved provides a kind of laser light target that can reduce ambient light to laser signal imaging influence.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of laser light target, comprise target center, frame folder, optical glass, narrow band pass filter, optical projection film, white balance film and Ahmedabad filter coating, the frame folder is housed around the target center, and target center is formed by stacking from top to bottom successively by optical glass, narrow band pass filter, optical projection film, white balance film, Ahmedabad filter coating and optical glass.
The beneficial effect that the utility model compared with prior art has is: target center of the present utility model is by optical glass, narrow band pass filter, the optical projection film, the white balance film, Ahmedabad filter coating and optical glass are formed by stacking from top to bottom successively, optical glass has very high transparency and flatness, can allow light is fine to be passed, and can compress other light film, narrow band pass filter can be with the light of specific wavelength by allowing the light reflection (or decay) of its all band, the optical projection film can see through the image that screen is seen the screen back, the white balance film can reduce the original color of object, the Ahmedabad film can be subdued light and harmful radiation, can't reduce simultaneously the contrast of object, so well guarantee the clear of laser signal that area array CCD receives, improved the precision of measuring.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross-section structure enlarged drawing of the utility model target center.
Among the figure: 1 is that target center, 2 is the Ahmedabad filter coating for white balance film, 7 for optical projection film, 6 for narrow band pass filter, 5 for optical glass, 4 for frame folder, 3.
Embodiment
As shown in Figure 1: a kind of laser light target of the utility model, comprise target center 1, frame folder 2, optical glass 3, narrow band pass filter 4, optical projection film 5, white balance film 6 and Ahmedabad filter coating 7, frame folder 2 is housed around the target center 1, and frame folder 2 can not only fine fixedly target center 1, and ease of assembly; Target center 1 is formed by stacking from top to bottom successively by optical glass 3, narrow band pass filter 4, optical projection film 5, white balance film 6, Ahmedabad filter coating 7 and optical glass 3.
Optical glass 3 has very high transparency and flatness, can allow light is fine to be passed, having the visible range height sees through, do not have and select to absorb characteristics such as painted, and can compress other light film, narrow band pass filter 4 adopts narrow-band pass filter 650NM, can filter 650NM all light in addition, and present desired image clearly, optical projection film 5 can see through the image that screen is seen the screen back, under different light, the light color that object sent is also different, be subjected to that the influence of light source causes, so just reduce the original color of object with white balance film 6, Ahmedabad film 7 employing density are 5.0 Ahmedabad film, outward appearance is the thin aluminum film of silver color, can subdue light and harmful radiation, can't reduce the contrast of object simultaneously, so just well eliminate the influence of ambient light imaging, guarantee the clear of laser signal that area array CCD receives, improved the precision of measuring.
