The integrated test evaluation of the photoelectric system is realized, the test result and the test curves are displayed simultaneously on the test interface, and the test recording table is automatically output, so that the test accuracy and test efficiency are improved, and the difficulties of optical axis adjustment are solved.

Description

technical field [0001] The invention relates to the technical field of testing photoelectric systems based on four-quadrant detection, in particular to a device for four-quadrant detection photoelectric systems, and the online installation and adjustment of four-quadrant detection photoelectric systems, instantaneous visual The technical method of field measurement also relates to the performance test method of the four-quadrant detection photoelectric system after online installation and adjustment based on the four-quadrant detection photoelectric system. Background technique [0002] For photoelectric systems with four-quadrant detection, test systems and test methods are important means to test products. Mainly irradiate the target with active and semi-active laser beams, and the photoelectric system using the four-quadrant detection uses the laser reflected by the target to track the target. The performance of the photoelectric receiver, such as sensitivity, dynamic ran...

Problems solved by technology

[0004] Difficulty in adjusting the optical axis: Since the two-dimensional turntable is placed vertically and carries the product to swing horizontally, the product is affected by gravity during rotation, making it impossible to accurately position the mechanical axis. It takes multiple tests to align the mechanical axis and optical axis of the product, the assembly and adjustment process is complicated, and the debugging cycle is long

[0005] Low measurement efficiency and poor accuracy: the two-dimensional turntable is a manual low-precision turntable, and the rotation angle can be judged by the naked eye by manually rotating the adjustment knob, and because the turntable has an angle return error, the zero positioning accuracy of the product in the reverse direction test cannot be guaranteed; Human error is unavoidable when personnel read the test data, so the test accuracy is poor; in order to accurately test the linearity of the field of view, it is stipulated that the test should be carried out at a step size of 0.1° within the ±1.5° field of view, and each test records 4 Group data, large amount of data records, low test efficiency
