Analysis for Galileo optical experiment

The generally Galileo optical experiment is analysied, included the analysis to components used in the experiment. The paper is focused on the analysis to the operational principle and working course of laser transmitter, and the working concept of PAT subsystem (pointing, acquisition, and tracking). The experimental result is analyzed detailedly. Contrapose to the failed receiving from the effect of atmosphere and weather, the feasibility of the scheme that adaptive optics techniques to mitigate the atmosphere-induced signal fades is discussed. At the same time, to the problem that background light resulting in the performance of link worse, the feasibility of the scheme is discussed that interferential light, filler to restrict background light and provided the referenced opinion to the research of deep space optical communication of China.
