Abstract

This paper presents an optical current sensor which is based on introducing nonuniform period onto a fiber Bragg Grating (FBG) by embedded it in a magnetostrictive composite with tapering shape. The interaction of the composite with an external magnetic field yields a strain distribution that widens the FBG spectrum through frequency chirping. The sensor has been investigated theoretically by modeling and experimentally by prototyping.
