光纤Bragg光栅应变、温度区分测量方法研究

Research on discriminating measurement of temperature and strain using fiber Bragg grating sensing methods

分析了光纤Bragg光栅应变和温度交叉敏感的物理机制,将目前存在的多种解决方案归纳为三类,即:矩阵运算法、参考FBG法、采用两个包层直径不同的FBG法,并全面介绍了各种解决方案的原理及优缺点。

Based on the analysis of physical mechanism of the strain and temperature cross sensitivity, catego- rizes several solutions into three groups ,such as matrix operation, reference FBG and two FBGs with different cladding diameters, then describes principle ,advantage and disadvantage of these solutions.
