Abstract

Abstract

Currently,Fiber Bragg Grating which has become a new way of monitoring and detecting has the feature of removing electromagnetic interference,high sensitivity,environmental adaptability,long life in the filed of strain monitoring of bridge,steel structure,etc.But the FBG wavelength shifts with temperature changing has greatly affected the property of monitoring systems.It is necessary to using FBG temperature compensate technology.Combining a certain project of steel structure,this article referred to a new FBG senor and described its insensitive temperature technology can accurately strike off the affection of temperature.It has achieved the aim of long-sterm health monitoring.
