摘要
紫外光通信是上世纪末发展起来的一种新兴的光学信息传输技术.本文将详述紫外光通信实验中的一些关键技术,包括紫外光源的高速调频系统,高灵敏度探测系统的设计,以及微弱信号检测和处理模块等.本紫外光通信系统在半双工工作方式下完成了高质量语音和高速数据传输,其最大传输波特率达到了9600bps,两倍于2000年美国GTF公司提供给美国海军的紫外光通信系统的传输波特率.而且,在某些距离上还能够实现非视距通讯,此通信方式具有广泛的民事和**应用前景.
Abstract
Ultraviolet light communication is a new means of optical information transmission technology developed since 1990's. In this paper, some key technologies developed from the experiment are described in detail. These technologies include the designs of high speed UV source frequency modulator, high sensitive optical receiver system and the design of weak signal detect and process modular, etc. The UV communication system has accomplished good voice and high speed digital data bidirectional communication in semi-duplex way and its maximal communication baud rate is up to 9600 bps which is twice as the baud rate of the UV communication system made by GTE company for USA navy in 2000. Furthermore, in some distance, the system can achieves a non-line-sight communication.
