摘要：
A fiber-optic sensor based on the extrinsic Fabry-Perot interferometer (EFPI) is demonstrated to measure de magnetic fields (100-35000 nT), A Metglas (Fe77.5B15Si7.5) wire-based magnetostrictive transducer is used as the reflector in two quadrature-phase shifted EFPI sensor elements which are used to overcome phase ambiguity in the interferometric sensor. The simple sensor geometry gives both relatively low-vibration sensitivity and better than 99% compensation for thermally induced fluctuations.
