基于布里渊增益的单端分布式光纤传感技术

A Distributed Optical Fiber Single-end Sensing Technique Based on Brillouin Gain

摘要:

本文对基于布里渊增益的分布式光纤传感技术进行了理论分析 ,并针对一些特殊应用领域提出了一种能够以单端方式工作的新型传感结构。光纤端面的菲涅尔反射光和信号检测的时序控制在该结构中被应用 ,以实现温度或应变的测量。初步的实验也表明该方案是可行的

Abstract:

This paper describes the principle of distributed optical fiber single-end sensing technique based on Brillouin gain.To fit the need of single-end test in some applications,a new sensing configuration,in which Fresnel reflex and the scheduling of two signals are used,is brought forward.The primary result confirms this configuration is feasible.
