Metglas based extrinsic miniaturized fiber optic magnetic field sensor system has been designed and fabricated for measuring DC magnetic fields. A simple geometry and modification of sensor gage show 98 percent suppression of thermally induced output variation and 92 percent of fringe visibility. A single-board microcomputer is used for accurate signal demodulation and calibration. The system has demonstrated a resolution of better than 100 nT over a range of 100 nT to 40,000 nT.
