Abstract

We review the development of magnetic sensors based on fiber optic technology including magnetostrictive and Faraday rotation sensors. Magnetostrictive sensors utilize fiber interferometers to measure the field-induced change in length of a transducing material. in Faraday rotation sensors, an external magnetic field causes a rotation of linearly polarized light propagating in the fiber itself. The working principles, advantages, and limitations of each technique are presented and current research and development efforts are summarized.
