| 摘 要： | 利用长周期光纤光栅（LPFG）和高双折射光纤（HBF）环镜的谐振波长对温度和应变的灵敏度差异,设计了温度和应变同时区分测量系统。在理论分析的基础上,分别测定了LPFG以及HBF环镜谐振波长对温度和应变的灵敏度系数,构建相关系数矩阵方程,实现温度和应变区分测量。实验测得该系统的温度和应变测量精度分别为±0.36℃和±13...

| Abstract: | A simultaneous measurement system of temperature and strain is proposed using a long period fiber grating(LPFG) and a high-birefringence fiber(HBF) loop mirror,based on their resonant wavelengths corresponding to different temperatures and strain sensitivities.Based on the theoretical analysis,the resonant wavelength response sensitivities to temperature and strain for long-period fiber grating and high-birefringence fiber loop mirror are experimentally determined,respectively.And then,the corre... |
