【摘要】 采用自适应光学系统对传输光束进行相位校正,是建立高速高可靠性的大气相干激光通信链路的有效手段。本文首先阐述了应用于大气相干激光通信的自适应光学技术的关键问题,然后介绍了直接混频接收和光纤耦合接收两种通信系统在相位校正条件下的通信性能的研究进展,以及讨论了相干激光通信背景下相位残差和斯特列尔比两个自适应光学系统性能指标的适应性。最后本文还对面向大气相干激光通信的自适应光学技术下一步需要解决的问题进行了描述。更多还原

【Abstract】 Wavefront compensation using adaptive optics system is a necessary and effective way for building coherent optical communication link with high speed and stability through atmosphere. This article begins with the explanation of the key problems of adaptive optics system required by coherent optical communication. It then reviews the recent progress of calculating the signal to noise of coherent optical communication based on direct heterodyne and single mode fiber coupling after wavefront compensation, and discusses the adaptability of using wavefront variance and Strehl ratio to judge the performance of adaptive optics system in the communication scenario. This article concludes with the description of the works need to be investigated for constructing the complete theoretical modal of adaptive optics technology oriented coherent optical communication through atmosphere in future更多还原
