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.
系統採用光濾波器，大大降低了襍散光的乾擾，具有較高的信噪比。
The principle and characteristic of excited light source, interference optical filter, transmission optical fiber and optical detector are discussed.
論述激發光源、乾涉濾光片、傳輸光纖、光探測器的原理及特性。
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.
在接收系統中，引進窄帶乾涉濾光片，減少背景光的乾擾，增加信號光透射率，改善信噪比。
