摘要：

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