摘要
基于光纤非线性效应,设计并搭建出一套布里渊散射光与瑞利光拍频测量温度的实验装置,用布里渊频移量对温度系数进行标定,并采用三种不同方法进行数据处理,结果表明采用频移量均值线性拟合结果较好,得到的布里渊温度频移系数为1.005 MHz/℃,该温度传感系统的测量精度为0.7℃。
Based on the nonlinear effect of fiber,a temperature measurement system based on Brillouin and Rayleighsca ttered light beat frequenc ie s is designed and developed. The temperature cofrequency shift , three different methods was used for data processing. The results using frequency shift mean, the Brillouin temperature coefficient is 1.005 MH/℃ the tempe rature sensing system is 0.7℃ .
