Abstract

In this paper, a magnetic field sensor based on Terfenol-D coated optical fibers is proposed and demonstrated. In our scheme, standard single mode fibers are coated by a thick layer of a magnetostrictive composite consisting of Terfenol-D particles dispersed in a polymer, which is then utilized as sensing elements. The magnetic field-induced strain on single mode fibers coated by the Terfenol-D was interrogated by an optical frequency-domain reflectometry (OFDR). The experimental results show that the sensitivity of the magnetostrictive fiber sensor depends on the coating characteristics including the surface of coated optical fiber. The sensitivity of the proposed sensor is 0.175 με/mT.
