Signal analysis of a polarimetric fiber optic sensor for dynamic strain monitoring

Marcin S Bieda, Andrzej W. Domański, Dawid Kuchta, Piotr Lesiak, Tomasz R. Woliński


Polarimetric fiber optic sensors have many advantages over other fiber optic sensors and strain gauges. As opposed to Fiber Bragg Grating sensors, polarimetric fiber sensors can be constructed with very simple, portable and robust experimental setup. In the paper we propose two methods of the polarimetric sensor output signal analyzing. First method is based on depolarization phenomena, and calculates degree of polarization (DOP), second one uses Fast Fourier Transform to analyze dynamic sensor response. Usefulness of both methods has been shown and experimentally proven.
