Distributed polarimetric measurements for optical fiber sensing

摘要

Distributed polarimetric measurements based on Rayleigh scattering in single mode optical fibers are effective tools for the characterization of the polarization properties of fibers. Since these properties are easily influenced by external perturbations, distributed polarimetric measurements turn out to be an interesting approach to distributed fiber optic sensors. This paper reviews the field putting emphasis on its underlying principles and unique applications, such as magnetic field mapping and twist measurement.
