摘要

针对以LED（发光二极管）为光源的紫外光通信系统中接收端紫外光信号较弱的问题

对基于PMT（光电倍增管）的紫外光语音接收系统提出了一套完整的优化设计方案

系统包括电流/电压变换、放大、滤波以及整形电路等

利用模块化设计思想完成了各部分电路的设计与实现

并进行了仿真和实验测试。结果表明

当光源采用1.6mW的紫外LED发射速率为4.8kbit/s的语音信号时

系统在10m半径范围内准视距条件下可以正确恢复出语音信号

话音清晰完整。

Abstract

As the ultraviolet light signal at the receiver end of ultraviolet communication systems with LED as the light source is weak

this paper proposes a set of complete optimized design scheme for photomultiplier-based ultraviolet voice-receiving system.This system consists of I/V conversion

magnification

filtering and shaping circuits

which are all designed and realized using modularized design ideas.Simulation and experimental test results indicate that when the light source 1.6mW LED emits voice signals at the rate of 4.8kbit/s

the system can correctly recover distinct and complete voice signals within a radius of10 mand in quasi line of sight.
