摘　　要：对伽利略光学实验进行了全面的分析,其中包括实验装置和元器件的分析,并重点分析了实验发射系统的工作原理和工作过程,对准、跟踪系统的工作原理和工作方式。并对实验的结果进行了详细分析,针对实验中出现的因大气影响而导致接收失败,讨论了采用自适应光学对大气影响进行补偿的方案的可行性,对于因背景光过强而导致的链路性能劣化,分析了采用干涉滤光片对背景光进行抑制的可行性,为我国将来开展深空光通信的研究提供参考。Analyzed generally Galileo optical experiment, included the analysis to the equipment and the components used in the experiment. 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）. Analyzed detailedly the experimental result, Contrapose to the failed receiving from the effect of atmosphere and weather, disscussed the feasibility of the scheme that adapthe optics techniques to mitigate the atmosphere-induced signal fades. At the same time, to the problem that background light resulting in the performance of link worse, disscussed the feasibility of the scheme that interential light filter to restrict background light and provided the referenced opinion to the research of deep space optical communication of china.
