摘要: 为了提高空间光通信的抗干扰能力,采用了一种基于二波耦合基础的新型差分光调制器件.实验结果表明,利用这种差分调制器实现的差分模式自由空间光通信,能有效抑制云团、雾等干扰因素引起的共模干扰,空间光通信的通信质量通过这种差分传输方式得到显著提高.Abstract: In order to improve the anti-interference ability of spatial optic communication,a novel optic differential modulation device based on two-wave mixing was adopted.Experimental results proved that the common-mode noise caused by cloud cluster,fog,etc,could be eliminated effectively with the help of differential mode spatial optic communication.The quality of spatial optic communication can be markedly improved by taking differential method.
