摘　　要：提出一种基于紫外激光器的"日盲"紫外激光通信系统,以深紫外激光器作为通信基站,用光电倍增管作为紫外光接收器,采用改进型的FSK调制方法和过零检测解调技术完成调制与解调。搭建了紫外激光通信系统实验平台,讨论了影响误码率的因素,最终实现了一个通信距离为0.1km、传输速率为0.6kb/s、误码率低于10-5的紫外激光通信系统。A solar-blind ultraviolet （UV） laser communication system based on ultraviolet laser is proposed. Deep UV laser used in this system as a communication base station, with a photomultiplier tube as a light re- ceiver, using improved FSK modulation method and the zero-crossing detection technology to complete the modulation and demodulation.An experiment platform of UV laser communication was built to discuss the in- fluence factors of bit error rate.Finally, a UV laser communication system was achieved whose communica- tion distance was 0. lkm, transfer rate of 0.6 kb/s, bit error rate less than 10-5 .
