夹持式温度自补偿光纤布拉格光栅应变传感测试技术
Laser & Optoelectronics Progress（2018）
Abstract
鉴于光纤布拉格光栅(FBG)应变测试时对应变和温度交叉敏感的特性,将温度补偿FBG结构与应变FBG结构串联,采用夹持式封装方式,根据温度FBG和应变FBG相对波长的变化确定被测结构的应变量.实验结果表明:温度FBG和应变FBG相对波长变化对温度的灵敏度仅为0.12 pm·℃-1,为温度FBG和应变FBG温度灵敏度的1.14％和1.15％;并实现了应变FBG测量的温度自补偿.夹持式温度自补偿FBG应变传感测试技术原理简单,实用性强,可被广泛应用于实际工程中.
