Abstract: This paper analyzed the basic theory and sensitivities of the Fiber-Bragg-Gating(FBG) in transducing temperature and strain.Based on those conclusion,we established the experiment system of the Fiber-Bragg-Gating(FBG) to show it's sensing characters,and introduced the composition structure of a light-path system as well as the characters of it's corresponding parts.The results of the experiments system indicated that FBG has a good ability to implement the measurement of temperature and strain,and proved the correctness of the analyses of FBG theory,as well as the rationality of the experiment system model.
