  • A kind of fiber Bragg grating(FBG) strain sensor with stainless steel tube jacket is presented in this paper. The sensor has wavelength sensitivity coefficient to strain of 1.19pm/με and excellent linearity was shown between the wavelength shift and the strain. The sensor can be bonded tightly to structure,which makes strain transferred effectively. It is very suitable for measurement of the strain in engineering.

Abstract: A kind of fiber Bragg grating(FBG) strain sensor with stainless steel tube jacket is presented in this paper. The sensor has wavelength sensitivity coefficient to strain of 1.19pm/με and excellent linearity was shown between the wavelength shift and the strain. The sensor can be bonded tightly to structure,which makes strain transferred effectively. It is very suitable for measurement of the strain in engineering.
