Intensity-modulated magnetic field sensor based on fiber Bragg grating
A magnetic field sensor based on the chirp effect of fiber Bragg gratings (FBG) was devised, and the relationship between the reflectance spectrum bandwidth and the magnetic induction intensity is deduced. The magnetic force from an energized spiral coil acts on the disk-shaped soft iron in the magn...
