Abstract

An optical magnetometer, which is capable of measuring static as well as dynamic magnetic fields, is presented. An all-fiber Marc-Zender interferometer, powered by a laser diode, was used to measure the strain of a metallic glass strip. Using a magnetic feedback technique and an AC-magnetic bias field, a minimum de-tectable field of 5pGauss in 1 Hz equivalent noise bandwidth was achieved. The magnetometer responds linearly from 0 Hz to a 3 dB bandwidth of 253 Hz and has a dynamic range of more than 100 dB.
