摘要

提出了一种新型的多路lpg光纤环路反射镜探测技术，并进行了实验验证。每个位移传感器由一个光纤环镜和一个长周期光栅组成。这种高反射率可变反射镜适合于由OTDR进行查询，并可在无串扰且温度无关的设置中进行多路复用。

New interrogation technique for multiplexing LPG-fiber loop mirrors based displacement sensors using an OTDR

A novel interrogation technique for multiplexing LPG-fiber loop mirrors has been proposed and experimentally demonstrated. Each displacement sensor is formed by a fiber loop mirror combined with a long period grating. This high reflectivity variable mirror is suitable to be interrogated by an OTDR and to be multiplexed in a crosstalk free setup with temperature independence.
