Abstract:
1. A fiber magneto-optic detection system comprising: a reference device for generating a reference magnetic field signal with known amplitude and shape at a measurement point; a magneto-optic probe for detecting magnetic field signal at the measurement point and converting the magnetic field signal into optical signal, in which the optical signal is carried by the received laser light for transmission and in which the magnetic field signal is superposition of the reference magnetic field signal and the magnetic field signal generated at the measurement point itself; a fiber device for conveying laser light and transmitting the optical signal sent by the magneto-optic probe and carried by the laser light to a power supply and signal processing module; and the power supply and signal processing module for emitting laser light, converting the optical signal into electric signal after receiving the optical signal, and demodulating and analysis the electric signal based on the reference magnetic field signal, so as to obtain the magnetic field information and/or current information of the measurement point itself.
