摘要
设计了一种分布式布拉格光纤光栅(FBG)传感器,给出了传感头的封装方法和传感阵列的工程铺设办法,熔封后的传感头增强了对泄漏点检测的灵敏性;进行了相应的实验,无石油泄漏处的光纤光栅的中心波长变化为Onm,而发生泄漏处的光纤光栅的中心波长变化为1nm,实验结果和理论分析是一致的。
A distributed fiber Bragg grating sensor is designed. The method for packaging the sensing head and the method for paving the sensing array in project are given. The detection sensitivity of the packaged sensing head to the leakage position is improved. A correspongding experiment is done. The experimental result shows that the center wavelength of the fiber grating has a change of 0nm without oil leakage and has a change of lnm with oil leakage. The experimental result is consistent with the theory analysis.
