| Abstract: | 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. |
