Temperature-Independent Fiber Bragg Grating Displacement Sensor
A novel technique for fiber Bragg grating displacement sensor temperature-induced wavelength-shift passive compensation is introduced. With a step thickness isosceles triangle shape cantilever beam, a fiber grating glued on the surface along the beam axis across the thickness border is employed to sense the free end displacement. The experimental sensitivity of 9.24×10-2 nm/mm is obtained, which agrees with the theoretical value 9.4×10-2 nm/mm very well.
