Abstract

In this paper a kind of optical collimation system for monitoring space-borne equipment is introduced. The flare image processing technology in the system is analysed specially. The processing speed is improved by the improved average filtering. According to flare image’s completion, the grayscale gravity technique or the circular fitting technique is adopted respectively, which can not only ensure the measurement precision but also extend the measurement range. The measuring stability is 0.22μm and the precision is better than ±0.5μm when the collimation distance is 1.5m under vacuum conditions by the experiment.
