interference light filter

基本解释

In order to obtain a higher SNR, an optical filter is used to reduce the interference of background light.
系统采用光滤波器，大大降低了杂散光的干扰，具有较高的信噪比。
The principle and characteristic of excited light source, interference optical filter, transmission optical fiber and optical detector are discussed.
论述激发光源、干涉滤光片、传输光纤、光探测器的原理及特性。
In the receiving system, the narrow-band interference filter is introduced in order to reduce the background light, increase the signal transmission rate, and improve the signal-to-noise ratio.
在接收系统中，引进窄带干涉滤光片，减少背景光的干扰，增加信号光透射率，改善信噪比。
