Abstract

A novel fiber optic accelerometer based on the integration of dual polarization fiber grating laser with cantilever-mass element is proposed and experimentally demonstrated. The applied acceleration is converted into a change in the beat frequency between the two polarization modes from the fiber laser. This new type of accelerometer has advantages of high sensitivity, absolute frequency encoding, capability to multiplex a number of sensors on a single fiber, and capability of separately tailoring the response sensitivity and natural frequency.
