Paper Abstract

A novel free-space optical (FSO) communication system is proposed in this paper. The beam divergence of transmit antenna is designed smaller and the receiving antenna is made by large aperture nonimaging optical system. A transmission mode of "small beam divergence and large receiving aperture" is designed, which can optimize the detection equation and improve the bandwidth, link distance and reliability of FSO system. The surface accuracy requirement of nonimaging optical system and the equipments are low. The pulse stretch caused by surface error has little effect to the bandwidth of FSO system, and satisfies the requirement of most communication.
