Abstract
A novel method for simultaneously measuring displacement and temperature us ing an in-fibre-Bragg-grating (FBG) based extrinsic Fizeau interferometric sensor is presented. The Fizeau cavity is formed by an FBG with low reflect ivity and a highly reflective surface. The FBG acts as both a reflector for the Fizeau interferometer and a temperature sensor, at the same time. Expe rimental results are provided which demonstrate the feasibility of this sen sor design.
