摘要
无线激光通信(WLC),又称自由空间通信或者大气激光通信,是一种以激光为载体的点对点通信.本文介绍了无线激光通信系统的工作原理,通过计算得出了系统的通信能力和通信质量将主要取决于激光光束的传播情况的结论,讨论了系统通信波长的选取,其发射系统,光学天线以及接收系统的设计关键,以及无线激光通信和当前主流通信方式的比较,展望了无线激光通信系统广阔的发展前景。
Wireless Laser Communication（WLC）, also called free space optical communication, is a kind of point to point laser communication. This paper introduces the WLC system principle, gets a conclusion that the system＇s communication ability and quality are mainly decided by the transmission of the laser beam through the computation, and discusses the selection of WLC wavelength, the key design of the sending system, optical antenna, receiveing system. WLC is also compared with today＇s other popular communication method in this paper. WLC has a wide prospect of application.
