摘要
基于布里渊光时域反射计(BOTDR)的传感原理,构建了分布式光纤布里渊温度传感测量系统,对4.25 km长度的光纤进行了温度传感试验。通过对试验结果的分析表明:该系统可以实现一定长度的光纤定点、定量的受热温度测量分析。对测量结果采用归一化方法处理,使测量结果更直观,分析快捷,精度更高。
Based on the sensing theory of Brillouin optical time domain reflectometry (BOTDR), the distributed optical fiber Brillouin temperature sensing system is built and is used to measure the temperature on the 4.25 km length optical fiber. The analysis of the experimental results shows that the system may determine the temperature at any points for a certain length optical fiber. The unitary method makes the experimental results more intuitionistic and more accurate.
