      Overview of space laser communications

      摘要:
      介绍了激光通信的基本过程和链路类型。着重调研了欧州空间局、美国、德国、日本以及国内激光通信的最新发展概况,给出了一些已成功应用的激光通信终端的详尽技术参数,如通信波长、通信距离、通信速度误码率、应用目的等,突出了每一种仪器的特点和优势,并对其光机结构进行了详细分析和展示。通过分析国内外的研究状况,指出激光通信面临的关键技术问题,以及未来激光通信发展的趋势和方向,为激光通信设备及其相关领域的研究提供了一定的参考。
      Abstract:
      This paper describes the basic process of laser communications and their link types firstly .Then, it focuses on the latest developments of the laser communications in the European Space Agency (ESA), the U-nited States, Germany, Japan, and domestic laser communication research , and also gives detailed technical parameters of some successful applications for the laser communication terminals in space , such as laser wave-lengths, communication distances, communication speeds, bit error rates, and application purposes.It high-lights the characteristics and advantages of each instrument in opto-mechanical structure, points out the key technical problems faced by the laser communications , as well as the future development of laser communica-tion trends and directions through the analysis of the research status at home and abroad , which will provide a reference for the study of laser communication equipment and its related fields .
