Abstract

A compact in-fiber integrated fiber-optic Michelson interferometer based accelerometer is proposed and investigated. In this sensing system, the sensing element consists of a twin-core fiber acting as a bending simple supported beam. By way of demodulating the optical phase shift, we can obtain the acceleration which proportional to the initial force applied on the central position of the twin-core fiber. A simple model has been established to calculate the sensitivity and resonant frequency. The experimental results show that such an accelerometer has a sensitivity of 0.09rad/g at the resonant frequency of 700Hz.
