Paper Abstract

In this paper we propose a novel kind of quasi-distributed vibration sensor based on the measurement of the polarization state of light. Its principle is based on the combination of mechanical transducers -which transform the mechanical perturbation into a birefringence variation- with fiber Bragg gratings. We show that several vibrations can be detected and localized at each transducer position with a frequency resolution of 1.25 Hz.
