Study of FBG stain sensor temperature compensation system
摘要
Abstract
In order to improve temperature cross-sensitivity phenomenon of the Fiber Bragg Grating strain sensor, the BP neural network method is adopted to realize temperature compensation system of the FBG strain sensor .The results of computer program and experiment illustrate that the method can separate the strain and the temperature exactly in the FBG strain sensor,solve nonlinear influence problem of the FBG strain sensor brought by temperature well and the measuring error for the strain is about 10-3.The method also restrains the influence of nonlinear effectively in the FBG strain sensor.关键词
