摘要 无线激光通信是指利用激光束作为载波在空间(陆地或太空)直接进行语音、数据、图像信息双向传送的一种技术。与其它几种通信方式相比,无线激光通信具有独特的优势无需授权执照、安全保密、实施成本相对低廉、建网速度快、协议的透明性、设备尺寸小、信息容量大。 Wireless laser communication using the laser beams as a carrier refers to trans- port voice, data, image information directly in a two-way transmission technology in space (land or outer space ) .Comparing with other several Communication ways, the wireless la- ser communication has the unique superiority: it does not need to be authorized the license; safe and confidential;the implementation cost is inexpensive relatively;the fishing net speed is quick; the agreement is transparency; the equipment size is small; the information capac- ity is huge.
