大应变光纤Bragg光栅传感器的研究
Research of Fiber Bragg Grating Sensor with Large Stain
摘要
Abstract
The fiber Bragg grating(FBG)sensor with the stain of 0 ~6 000 (xe is developed based on the long-term stain in fiber which is less than 3 000 με. By the external forces, the relative position of the fixed pivots are changed,which causes the axial deformation of the strain tube leading to the Bragg wavelengths shift in proportion of FBG attached at two ends of the adjusting tubes. Through loading, the sensor is stretched. The experimental results show that the response sensitivity of the sensor is 1. 783 pm / kg, the stain sensitivity is 0. 685 pm/με, and the maximum stain range could be 5 250με.关键词
