摘　　要：阐述了云南天文台1.2m望远镜卫星激光测距中所使用的光电探测器,并对它们的性能和使用效果做了比较。结果表明,C SPAD是目前测距精度最高的单光子探测器。同时还论述了激光测距的工作原理和近几年来云南天文台激光测距的情况。从对GPS35、36卫星的观测结果表明,云南天文台已具备了一定的对远程卫星的测距能力,为今后远程测距、测月打下了良好的基础。The detectors of satellite laser ranging (SLR) system in Yunnan Observatory are presented in this paper.The new detector CSPAD is compared with the old detector MCP for near and longdistance targets. Their characteristics and performances are analyzed.The CSPAD has highest accuracy for SLR.Moreover, the status of SLR in Yunnan Observatory in recent years are presented.According to the data obtaining from GPS 35?36,the SLR system in Yunnan possesses the capability for longdistance objects.It will be basic to further development of longdistance laser ranging.
