Optical Fiber Distributed Temperature MeasurementSystem and Precision Analysis

介绍了基于后向喇曼散射的分布式光纤测温系统 ,对系统的测温精度进行了分析 ,针对影响测温精度的主要因素提出了相应的处理方法 ,实验证明所得出的结论是正确的 ,方法是可行有效的。

We discuss the optical fiber distributed temperature measurement system which based on the optical fiber Raman backscattering,and then study the main factors which affect the measurement,further,put forward the methods for each factor to improve the precision.The experiments have verified that the conclusions are right and the motheds are efficient.Now this system has already applied in well loging.
