基于边缘滤波的FBG解调系统

摘要

实现了一种基于边缘滤波的FBG解调系统,系统采用宽带光源、隔离器、分束器、FBG、耦合器及边缘滤波器等光学元件,来采集变化的光信号,同时设计光电探测器进行光电信号转换及放大滤波处理,并采用NI USB-6361进行数据采集,将模拟信号转换为数字信号,最后采用Labview进行处理,最终得出所要测量值。%A fiber Bragg grating（FBG） demodulation system based on the edge filter is introduced,it uses several optical components,including broadband light source,isolator,beam splitter,FBG,coupler and edge fil ter to collect the change light signals.At the same time,a photoelectric detector is designed to complete the photo electric signal conversion,and NI USB-6361 is adopted for the data acquisition and analog-to-digital conver sion.The measured value is obtained by Labview.
