摘要

布里渊散射光频域分析技术（BOFDA）

是一套通过测量连续泵浦光和连续探测光相互作用后产生的布里渊散射光所确定的基带函数的脉冲响应

运用相关计算方法确定传感光纤上物理信息的综合系统。与其它分布式光纤传感器相比

BOFDA可在窄基带下操作

具有分布式、高信噪比、高空间分辨率、低成本、多频信号平行测量和处理、信号动态范围大等优点。本文对BOFDA用于测量应变和温度的基本原理进行了介绍

并对前人做的室内、现场试验进行了概括和总结。

Abstract

BOFDA is a comprehensive system

which measures the pulse response of the baseband transfer function.The function is determined by Brillouin spectrum which is caused by the interaction between continuous pump laser and probe laser.The physical information along fibers is calculated by some relative math formulas.Compared with other distributed optical-fiber sensors

BOFDA has the advantages of low signal-to-noise-ratio

high special resolution and low cost.It provides the possibility of narrow-bandwidth operation and parallel measurements with different modulated frequencies.This paper gives an explicit introduction of the principles of temperature and strain measurement using BOFDA technology.This paper also summarized the results of laboratory and field tests that did by some researchers previously.
