Paper Abstract

A compact fiber optic Michelson interferometer based accelerometer is proposed and demonstrated. In this sensing system, two optical fibers have been used as the differential sensing element. By way of demodulating the different optical phase, we can obtain the acceleration which proportional to the initial force applied on the central position of the two fibers. A simple model has been built to calculate the sensitivity and resonant frequency. The experimental results show that such an accelerometer has a sensitivity of 0.42rad/g at the resonant frequency 600Hz.
