摘要
采用不锈钢管对光纤布喇格 (Bragg)光栅进行封装 ,封装后的光纤光栅作为应变传感器 ,灵敏系数为1 .1 9pm / με ,Bragg中心反射波长与应变呈良好的线性关系。传感器能够与被测结构紧密结合 ,保证应变的有效传递 ,便于安装 ,适于实际工程中的应用。
A kind of fiber Bragg grating(FBG) strain sensor with stainless steel tube jacket is presented in this paper. The sensor has wavelength sensitivity coefficient to strain of 1.19pm/με and excellent linearity was shown between the wavelength shift and the strain. The sensor can be bonded tightly to structure,which makes strain transferred effectively. It is very suitable for measurement of the strain in engineering.
