激光通信综合实验演示仪设计

摘要

In order to demonstrate the basic principle of laser communication technology, this paper introduces the design principles and working methods of a laser communications experimental instrument. The dual mode laser emission, photoelectric conversion, power amplifier and band-pass filter circuits are designed to receive laser signals that are collected by photoelectric detector, and reducting the signals realizes demodulation. This instrument has stable performance, convenient operation, and realizes the laser modulation and communication demonstration experiment of the union, which obtains a good teaching result in practical applications.%为了演示激光通信技术的基本原理,介绍了一种激光通信综合实验演示仪的设计原理和工作方法.设计出双模式激光发射、光电转换、功率放大和带通滤波相结合的电路,接收光电探测器采集的激光信号,并还原信号实现解调.该实验仪性能稳定、操作方便,并实现了激光调制与通信演示实验的结合,在实际应用中取得了良好的教学效果.
