摘　　要：叙述了云南天文台1.2m望远镜激光测距系统中应用多种手段,如:机械快门、发散角调整、距离门、光谱滤波、空间滤波,解决了可门控的雪崩二极管的动态范围问题,实现了远、近卫星的黑夜激光测距和部分近地卫星的白天激光测距。A series of methods,such as the mechanical shutter,the divergent angle alignment,the distance gate,the spectral filter,the space filter applied to the SLR at 1.2m Alt-Az telescope of Yunnan Observatory, are introduced in this paper. Problems of dynamic ranging of C-SPAD were solved. SLR was realized to LEO and high-orbit satellites during the night time and to some LEO in the daytime.
