Abstract:

A new versatile calibration system for multi-spectral axis parallelism is designed. The parallel light coming from the collimator is incident to each electro-optical system of the equipment by the parallel translation of the collimator, and the white target, dim light target and IR target given by the collimator are used for the calibration of the multi-spectral axis parallelism. The spatial position system aiming at locating the collimator, built by the principle of WMPS spatial angle measurement and the PNP question in vision metrology, is used to guarantee the precision of the parallel translation. The system is suitable for a variety of electro-optical equipments; it can realize auto detection and display the optical axis deviation in digital form, obtaining good versatility and expansibility.
