摘要
海水对激光信号衰减很大,为了从大量背景光和干扰光中接收到微弱信号,设计一个滤波器,在接收前端过滤掉背景噪声和干扰噪声。因此设计一个窄带干涉滤光片,并用Needle法和Tunneling法对此膜系进行设计优化。
In underwater laser communications system, the laser signal is attenuated greatly by water. In the receiving system, signal need to be filtered from background noise and interference noise in the receiver front-end in order to receive the faint light signals. The narrow-band interference filter will be designed and optimized in Needle method and Tunneling method.
