Abstract: The optics system of large aperture parabolic mirror collimator is designed. The laser beam coordinate extraction system based on image acquisition and processing is developed. The displacement close-loop control system based on raster ruler is developed. The testing facility for photoelectric tracker optical axes boresight is implemented. The facility can be used to measure the optical axis boresight between laser, infrared, TV, visual system of photoelectric tracker.

Key words: Large aperture collimator, Image process, Photoelectric tracker, Optical axes boresight
