摘要
对比了相干探测和直接探测，以及自由空间相干光通信和光纤相干通信，对相干自由空间激光通信系统的特点和关键技术进行了讨论，回顾了近年来国外在自由空间相干光通信领域内开展的有关研究计划。最后对相干光通信技术的应用前景进行了展望。
Abstract
The comparison between coherent detection and direction detection, and between free-space optical communication and fiber optical communications are made. The characteristics and key techniques of coherent optical communications in free space are discussed. International progress of space coherent optical communication is reviewed. Finally the application prospect of coherent optical communication technology is given.
