摘要
A high sensitive fiber Bragg grating strain sensor with automatic temperature compensation, comprising a FBG (1), a stick (2)axially connected with the FBG (1), and two flanges (5) that fix the free ends of both the FBG and the stick to the object (4) to be measured, specialized in the shift of the resonance Bragg wavelength of the FBG ΔλB = λB (1 — Pe )(d + L) / d * Aεm, where Pe is the photo-elastic constant, d is the distance between two mounting points of FBG, L is the length of the stick, Δεm is the strain change of the measured object.
