Orr, Philip and Niewczas, Pawel (2010) Polarization-switching FBG interrogator for distributed point measurement of magnetic field strength and temperature. IEEE Sensors Journal, 11 (5). pp. 1220-1226. ISSN 1530-437X (https://doi.org/10.1109/JSEN.2010.2091124)

Abstract

We report on the design and implementation of a novel optical fiber system for dual point measurement of magnetic field strength and temperature. The system incorporates a polarization switching technique that enables ratiometric processing of the orthogonal circularly polarized reflections from low-birefringence fiber Bragg gratings. High-resolution magneto-optical measurement of either static or dynamic magnetic fields may be achieved while retaining the capability for serial multiplexing and temperature measurement. The system provides a practical solution to intrinsic fiber point measurement of magnetic field, leading to potential applications in adverse environmental conditions, where electronic or extrinsic optical technologies are unsuitable.
