摘要: 主要研究了基于后向喇曼散射分布式光纤测温系统的温度标定问题.在讨论了系统稳定性和系统测温精度的基础上,提出了关于系统温度标定的一个结论.接着,对参考光纤不同状态和不同缠绕半径下的附加损耗进行了实验.在科学分析的前提下,给出了系统温度标定的实现方案.实际系统的设计过程证明:结论是正确、合理的,对此类系统设计具有一定的指导意义.Abstract: Temperature calibration in a distributed optical fiber temperature sensor system based on Raman back-scattering was discussed. A very useful principle was presented on the basis of considering system stability and system temperature sensing accuracy. By measuring and studying the loss due to status and radius differences of the reference optical fiber, a solution on how to carry out calibration was also described. Experimentations indicated that not only the principle is reasonable and correct, but also it is helpful to the design of such a system.
