光通信以其高带宽和高信息量的优势,不久将应用于空间通信。美国宇航局(NASA)和欧洲空间局(ESA)以及很多国家的空间部正在加速开发地球轨道中自由空间激光通信技术。激光通信技术可用于轨道中卫星间的互相通信以及卫星与地面站的
Optical communications with its high bandwidth and high information capacity will soon be applied to space communications. NASA and the European Space Agency (ESA), as well as space agencies in many countries, are accelerating the development of free-space laser communications in Earth orbit. Laser communications technology can be used for inter-satellite communications between satellites and satellite and ground stations
