| 摘 要： | 针对分布式光纤温度传感系统(Distributed Optical Fiber Temperature Sensing System,DTS)在线测温精度不高的问题,提出了使用光纤布拉格光栅(Fiber Bragg Grating,FBG)解调仪对DTS进行温度补偿。对不带温度补偿的DTS进行了温度测量和数据分析,证明了进行温度补偿的必要性。设计了带温度补偿的DTS并进行了温度测试。实验结果表明,在使用FBG解调仪对DTS进行温度补偿后,DTS的温度精确度可以达到0.3℃。

| Abstract: | With the aim of online temperature measurement low accuracy issues about distributed optical fiber tem perature sensor system,a kind of using fiber Bragg grating demodulation for DTS temperature compensation is proposed.The temperature measurement and data analysis are conducted for DTS without temperature compensation,the necessity of temperature compensation is proved.The DTS with temperature compensation is designed,and the temperature tests are done.The results show that the temperature accuracy of DTS is 0.3℃ through the use of fiber Bragg grating demodu lation for DTS temperature compensation. |
