Abstract

In order to solve the problem that the current optical axis parallelism test device cannot satisfy the test problem of optical axis parallelism of each optical sub-system of multi-spectral photoelectric equipment, the present invention proposes a multi-spectral optical axis parallelism test device and a test method. The present invention uses off-axis parabolic mirrors, beam splitters, short-wave infrared cameras, wide-spectrum light sources, target targets and laser light sources to realize the simulation of wide-spectrum infinite targets. According to the imaging position of the simulated target in each optical subsystem, The parameters of each optical subsystem and the focal length of the collimator, and the calculation of the consistency of the optical axis between the optical subsystems, can complete the visible light imaging system, infrared imaging system, laser emitting system, laser receiving system, visual inspection system in multi-spectral photoelectric equipment. The test of the parallelism of the optical axis between the aiming system and the mechanical reference of the equipment can realize all the requirements of the optical axis consistency of the current optoelectronic equipment.
