| 摘 要： | 设计了一套基于声光频移技术的激光通信系统。与一般相干通信系统比较,该系统在信号发送端完成了光波的频移以及不同频率光波的光学拍频,而在接收端直接探测拍频信号的中频成分。最后完成通信速率为3MHz的实验验证,达到了设计效果。

| Abstract: | A laser communication system,has been designed based on acoustic-optic frequency-shift technology.Compared to coherent communication systems,the new system completed frequency-shift and beat-frequency in the transmitting terminal and it received intermediate frequency part of beat signal.A communication experiment has been achieved,and the communication rate was 3MHz.The result of the experiment coincides well with the theory. |
