摘　　要：讨论了大气激光通信系统光收，发端机的功能和基本组成。激光器和探测器是收发端机的核心部件，描述了它们的特点和性能。通常采用信标光和信号光分离的方法来实现光通信系统的搜索、捕获和跟踪功能。对可供选择的探测器ＣＣＤ、ＰＳＤ、４ＱＰＩＮ、４ＱＡＰＤ的特点进行了分析，选择的依据主要是接收视场角、灵敏度和位置分辨率。In this paper, the functions and fundamental structure of atmospheric laser communication system are discussed The features and performances of laser sources and detectors—the core components of the system are presented Commonly, the laser communication systems with the functions of ATP are practiced by separating the signal beam and the beacon beam The characteristics of the available detectors—CCD, PSD, 4Q PIN, 4Q APD are analyzed The selecting rules are mainly the receiving FOV, sensitivity and position resolution

关 键 词：激光通信系统 收发端机 激光器 探测器
