自由空间中卫星激光通信

Satellite Optical Communication in Free-Space

由于具有高速率、大容量、高保密性能的特点,自由空间激光通信成为空间通信中的一个重要发展方向。介绍了自由空间卫星激光通信系统的组成。在详细分析自由空间卫星激光通信系统工作原理的基础上,提出了发展自由空间卫星激光通信的几项关键技术。最后介绍了国内外空间激光通信的研究现状及发展动态。

Because of its characteristics of high speed, high capacity and high security, free-space optilasercal communication has become a new development trend. In this paper, the structure of the inter-satellite laser communication system in freespace is introduced. Based on the analysis of the system's operating principle, some new key technologies in developing inter-satellite laser communication are given .At last, domestic and overseas research efforts and developments are presented.
