Visible-light reconnaissance device based on CCD is applied to all kinds of weapons, CCD cannot work because of
saturation when it faces intense light. Sun is intense light source in nature and assignably influences CCD performance.
In this paper, aim is appraising CCD anti-sunlight ability, object reflection characteristic test system is designed, based
on typical background reflection characteristic including grant, sand and so on, complex circumstance is formulated and
test project is optimized with orthogonal design method, problem that is without test technology on CCD anti-sunlight
jamming is solved.
Infrared thermal imaging system generates image based on infrared radiation difference between object and background
and is a passive work mode. Range is important performance and necessary appraised test item in appraisal test for
infrared system. In this paper, aim is carrying out infrared system range test in laboratory , simulated test ground is
designed based on object equivalent, background analog, object characteristic control, air attenuation characteristic,
infrared jamming analog and so on, repeatable and controllable tests are finished, problem of traditional field test method
is solved.
Laser range finder has been equipped with all kinds of weapons, such as tank, ship, plane and so on, is important component of fire control system. Divergence angle is important performance and incarnation of horizontal resolving power for laser range finder, is necessary appraised test item in appraisal test. In this paper, based on high accuracy test on divergence angle of laser range finder, divergence angle test system is designed based on CCD imaging, divergence angle of laser range finder is acquired through fusion technology for different attenuation imaging, problem that CCD characteristic influences divergence angle test is solved.
Laser stealth is an important way of photoelectric stealth weapons systems. According to operational principle of laser range finder, we actively explore and study the stealth performance approval testing technology of laser stealth materials, and bring forward and establish the stealth performance field test methods of stealth efficiency evaluation. Through contrastive test of two kinds of materials, the method is correct and effective.
With the development of science and technology, photoelectric equipment comprises visible system, infrared system, laser system and so on, integration, information and complication are higher than past. Parallelism and jumpiness of optical axis are important performance of photoelectric equipment,directly affect aim, ranging, orientation and so on. Jumpiness of optical axis directly affect hit precision of accurate point damage weapon, but we lack the facility which is used for testing this performance. In this paper, test system which is used fo testing parallelism and jumpiness of optical axis is devised, accurate aim isn’t necessary and data processing are digital in the course of testing parallelism, it can finish directly testing parallelism of multi-axes, aim axis and laser emission axis, parallelism of laser emission axis and laser receiving axis and first acuualizes jumpiness of optical axis of optical sighting device, it′s a universal test system.
