The present invention relates to the technical field of performance evaluation of a photoelectric imaging system, in particular to an imaging detection distance test system based on a simulated targetand a light energy attenuator, in order to solve the problems that in the prior art, the test target is difficult to select, the measurement of the attenuation amount in the atmosphere in the test process is relatively difficult, and the accuracy and precision of the test result are low. According to the system provided by the present invention, the illumination of the observation target and thebackground of the environment scene is simulated and controlled by using two integrating spheres respectively, the target beam and the background beam are simultaneously projected onto the light curtain for superposition, the light curtain pattern is used to simulate observation objects of different illumination, sizes and contrast, and by changing the area of the parallel beam transmission crosssection, the attenuation amount of the transmitted light energy can be simulated and adjusted.
Description
technical field [0001] The invention relates to the technical field of photoelectric imaging system performance evaluation, in particular to an imaging detection distance testing system based on a simulated target and an optical energy attenuator. Background technique [0002] In the process of installation and adjustment and performance evaluation of the telescopic photoelectric imaging system, the detectable distance and recognition distance of the system are an important technical index for system performance evaluation. In the actual test process, because it is difficult to find the target of setting distance, setting size, setting illuminance and contrast in nature, the detection and recognition distance test of the photoelectric imaging system can only select some existing targets and scenes for testing , it is difficult to obtain a large number of observation targets and scenarios that meet the requirements, thus limiting the accuracy of the test results. On the othe...
