A Fiber Fence System Based on M-Z Interferometer
基于M-Z干涉的光纤围栏系统实验研究

Fiber fence is a kind of distributed fiber sensing system.In this paper,the feasible techniques for fiber fence using M-Z interfero technique is discussed.A practical fiber fence system is builded and realized.The principle and structure and also the experimental results are presented and discussed.When set the AD convert speed as 20 MHz,the theoretic location accuracy of 10 m is achieved.
