Problems solved by technology
[0004] At present, most of the photoelectric stabilization system stability measurement devices established by scientific research institutes and testing departments are special-purpose testing equipment. In order to ensure reliable performance and accurate and unified parameter values, it is necessary to solve the problem of traceability. The photoelectric autocollimator has established some calibration specifications and calibration devices, but these calibration devices mainly solve the small-angle traceability under static conditions, and are not suitable for the dynamic parameter calibration of the stability measurement device of the photoelectric stabilization system. At the same time, some test documents The photoelectric theodolite was used to calibrate the stability measurement device of the photoelectric stabilization system, but only the angle calibration was completed, and it could not reflect the dynamic characteristics of the system, so it was difficult to meet the requirements
[0005] To sum up, in the prior art, there is still no effective solution for the calibration of dynamic parameters suitable for the stability measurement device of the electro-optical stabilization system.
