Abstract

We propose a polarimetric fiber optic vibration sensor. The principle is based on the evolution of polarization when the constraint (vibration) is applied on a sensitive zone of the sensor. We study the effects of a vibration application on our system with a continuous frequency and the polarization evolution on the Poincaré sphere. The study has demonstrated a very good accuracy and a good agreement between the theoretical and the experimental results were achieved.
