摘要
提出并实现了一种可满足工程实用要求的分布式光纤布拉格光栅解调系统。该系统通过可调谐光纤F-P滤波器的连续扫描实现波长信号的解调。该传感系统扫描带宽50nm,单点工作带宽5nm,对一般应用系统每根单纤可设20～30个点,分辨力5pm。
A distributed FBG demodulation system meeting the practical requirements in projects is proposed and demonstrated. An optical fiber Fabry-Perot tunable filter is used in the system to demodulate the sensing signal. The scanning bandwidth of the system is 50nm and the working bandwidth of each point is 5nm. 20-30 FBGs can be bedded in a single optical fiber in the system and the resolution is 5pm.
