摘　　要：针对2013年9月6日美国宇航局(NASA)发射的月球大气与尘埃环境探测器飞船上进行的月球激光通信演示验证(LLCD),从实验设计和后续发展方面进行综述。实验中,飞船上的LLCD太空终端与主要的月球激光通信地面终端或与欧洲空间局的月球激光通信地面系统完成双向通信,而与美国喷气推进实验室的月球激光通信"光通信望远镜实验室"(OCTL)终端仅进行下行链路通信。LLCD系统还进行了优于厘米精度测距的双向飞行时间测量。未来NASA的激光通信中继演示验证任务将基于LLCD系统的相关设计。最后对LLCD的启示进行了讨论。We review the experiment design and development of the lunar laser communication demonstration （LLCD） on the Lunar Atmosphere and Dust Environment Explorer spacecraft launched by the National Aeronautics and Space Administration （NASA） of USA on September 6th, 2013. When the space terminal is in orbit, bidirectional communications are performed with the main lunar laser communication ground terminal or with the European Space Agency＇s lunar laser communication optical ground system, but only downlink communications are performed with the Jet Propulsion Laboratory＇s lunar laser communication optical communications telescope laboratory （OCTL） terminal. Besides laser communication, bidirectional time-off light measurements are performed by LLCD system with sub-centimeter ranging accuracy. The future NASA laser communication relay demonstration will be developed on the basis of LLCD system. Finally we discuss the knowledge learned from LLCD.
