传感光纤光栅高温环境下反射率特性研究
Research on reflectivity characteristics of sensing fiber Bragg grating under high temperature environment
摘要
Abstract
The paper designs the molecular structure model based on the principle of optical fiber photosensitive,introduces the effect of high temperature time on the service life of fiber Bragg grating (FBG) with the FBG reflectivity as the major indicator,and describes the relationship between the reflectivity,the temperature and the time with the theoretical formula.The results are simulated and analyzed by constant temperature test at 330℃,400℃ and 500℃,and obtains the conclusion that the high temperature FBG has a long sensing life in the 330℃ environment.关键词
