ABSTRACT:
A differential polarimetric fiber optic sensor is disclosed in which a local compensating fiber section is spatially separated from a remote sensing fiber section by input and output polarization-maintaining fibers in order to permit the remote passive interrogation of the remote sensing fiber section by the direct polarization analysis of the light at the output of the local compensating fiber section.
