Abstract

This paper presents an investigation of magnetostrictive material-in-clad optical fibers for distributed magnetic sensing. A layer of magnetostrictive material (nickel or Terfenol-D) in the clad of conventional single mode fiber (SMF) is introduced to induce a strain when a magnetic field is applied. The sensor response is measured by using the Rayleigh backscattering frequency shift method. The results show that the frequency shift is directly proportional to the applied magnetic field. The sensor sensitivity for both nickel and Terfenol-D is 203.13 GHz/mT and 339.61 GHz/mT, respectively. Terfenol-D shows a better performance compared to nickel.
