摘　　要：自由空间光通信是一种通过在自由空间传输激光信号来实现点对点、点对多点或多点对多点间语音、数据、图像信息的双向通信技术。光学接收天线是自由空间光通信系统的关键部件。文中分析了卡塞格伦系统作为自由空间光通信系统中光学接收天线的可行性,讨论了其设计参数间的相互关系,并在数值计算的基础上给出一个具体的设计方案。Free-Space Optical Communication is a promising technology in transmitting laser signals in the atmosphere channel and realizing the communication of voice, image and data between point-to-point, point-to-multipoint and multipoint-to-multipoint. Optical antenna system is the important part of FSO communication system. Based on the theoretical analysis and numerical calculation, this paper discusses the feasibility of Cassegrain system as the optical receving antenna in the FSO communication system, and also gives a design of the optical receving antenna.
