Abstract
A differential temperature sensor based on fiber-optic Bragg-grating elements is described. A high sensitivity to thermally induced Bragg wavelength shifts is obtained using an interferometric detection approach. Results presented show a temperature resolution of <0.05 degrees C, corresponding to a Bragg wavelength shift resolution of <6*10/sup -4/ nm.Keywords
