Abstract : An optical fiber waveguide for detecting magnetic fields. The optical fiber waveguide includes therein an array of discrete elongate magnetized particles, all polarized in the same direction with their axes generally parallel with the longtiduinal axis of the waveguide, which in the presence of a time-varying magnetic field are subjected to magnetostrictive effects and undergo linear dimension changes to cause a related longitudinal dimension change of the optical fiber waveguide whereby a laser beam passing longitudinally through the waveguide is subject to phase shifts detectable by interferometry.
