narrow bandpass filter

The condition of the incoherent illumination , the half bandpass width of the narrow bandpass filter and the ac-curacy of the scanning grating are discussed too .

还讨论了非相干照明的条件，窄带滤光片的带宽和扫描光栅的精度要求。

This paper describes a new design method for a narrow bandpass filter .

本文叙述了一种新型的窄带带通滤波器的设计方法。

A kind of Narrow Bandpass Filter with Single Frequency Output

一种单频输出的窄带带通滤波器

These narrowband multi-channel filters and narrow bandpass filter arrays show good filtering features and can be utilized in many optical applications .

两种类型的滤光片都展示了良好的光学特性，在光学器件、光通讯等领域都有良好的应用前景。

This method is to use a bi-resonant narrow bandpass digital filter with chirp Z-transform to realize the narrow band spectral analysis .

这种方案采用双谐振窄带数字滤波器并结合Chirpz-变换算法来实现窄带频谱分析。
