摘　　要：分析空间激光通信系统精跟踪技术发展现状,使用振镜和CCD相机器件搭建了一套精跟踪系统。对CCD开窗口、光斑中心算法、光斑检测精度和补偿函数设计等内容进行了研究。完成精跟踪模拟实验,结果表明系统视轴稳定精度优于3μrad,符合精跟踪对视轴稳定的要求。Technical state of fine tracking in space laser communication was analyzed. A kind of experimental device was set up with scanning galvanometric and CCD cameras. The key technologies on region-of-interest of CCD, center location algorithm of formula, precision of spot detection and compensation function were researched. Simulation experiment was carried out, what had been proved the precision of line of sight stabilization was superior to 3 urad, meet the requirements of laser communication system.
