准分布式FBG对应变和温度双参数分离测量的实现
The Implementation of Two-Parameter Measurement of Strain and Temperature Using Quasi-Distributed FBG
摘要
Abstract
In order to solve the cross sensitivity problem of strain and temperature measurement existing in Fiber Bragg Grating, a scheme that implement two-parameter measurement of strain and temperature by placing two FBG at upper and lower end face of a bearing beam is presented .This scheme can both overcome the restriction of traditional two-parameter measurement method and simplify the separation algorithm .Calibration and measurement experiments results indicated that the response curves of strain and temperature demonstrate good corresponding relationship in the range of 0~100℃and 0~40MPa, and the maximum error is 3.7% and 4.2% respectively.This scheme is feasible to locate the position of strain point in quasi-distributed FBG , and has high application value .关键词
