Simultaneous Strain and Temperature Measurement Using Single High-duty-cycle Sampled Fiber Bragg Grating
Simultaneous Strain and Temperature Measurement Using Single High-duty-cycle Sampled Fiber Bragg Grating
摘要
Abstract
A novel and simple fiber grating sensor based on high-duty-cycle sample fiber Bragg grating is proposed and demonstrated experimentally. This type of sensor can measure strain and temperature simultaneously with merits of low cost, high sensitivity and immunity to electro- magnetic interference. The sensor has an accuracy of 20μεand 0.8 ℃over a strain range of 500~1 500 με and a temperature range of 5~36 ℃under experimental conditions.
