摘要

分布式光纤传感器尤其是干涉型光纤传感器以其特有的优点近年来成为研究的热点。针对长周界大范围设施的实时监测问题

阐述了双Mach-Zehnder环监测系统的原理。根据入侵干扰信号的特点

改进了原有的定位方法

提出了一种二次相关的方法以解决在入侵点定位过程中运算量与实时性的问题

并用实验数据加以说明此方法确实有效。

Abstract

Distributed fiber-optic sensor

especially interferometers

which has unique advantages become a hot topic in recent years.Principle of dual-ring Mach-Zehnder interferometer system is proposed to deal with the issue of monitoring of long perimeter and wide range of facilities.Acccording to the characteristics of invasion signal

an improved method which called dual-correlation algorithm is used to solve the problem of real-time and computation quantity in the pocess of localization of invasion point.The experimental datas indicate that this method really works.
