Fiber Optic All-Polarization Weak Magnetic Field Sensor Based on Sagnac Interferometer
A novel fiber-optic magnetic field sensor, based on a Sagnac structure, is proposed with the approach of polarization interference detection. The sensor takes advantage of common path interference, combining with a high magnetic field sensitivity sensing unit, composed of magneto-optical crystal, an...
