摘要
描述了一种光纤F-P传感器的多路复用解调技术,该技术采用一个4通道的粗波分复用器(CWDM)和一个40通道的密集型波分复用器(DWDM)构成多路复用系统,利用探测器对系统输出光能量进行检测,通过插值法对采集信号进行拟合计算,解调出反射光谱的波长值,实现了4支具有相同参数的F-P腔传感器的同时解调。
A multiplexing technology of Fabry-Perot（F-P）optical fiber sensor is proposed,which is composed of a 4-channel CWDM and a 40-channel DWDM.The intensities in each of the DWDM channel are detected,and the signals are used to calculate the wave length of the reflection spectrum.This technology can achieve the interrogation of 4 F-P optical fiber sensor.
