摘要
本文对基于后向 Raman散射分布式光纤测温系统中激光器中心波长的优化进行了分析 .在详细讨论了 Raman信号强度、温度灵敏度和系统工作稳定性等与半导体激光器中心波长之间的关系后 ,提出了优化选择中心波长的方法 ,并结合实例予以说明 .
In this paper,it is presented to analyze the distributed temperature sensor system based on the Raman backscattering to quantify the effect of varying pump wavelength.First,we study how to maximize the backscattering power from the endpoint of the fiber,then analysis the temperature sensitivity of the system,at last discuss the relationship between the system stability and the pump wavelength.Results are present after taking them into account.
