Patents Assigned to 3S HI-TECHNOLOGIES CO., LTD.
  • Patent number: 8841905
    Abstract: A system and method for fiber magneto-optic detection are provided, which belongs to the optical application field. The system comprises: a reference device (300) for generating a reference magnetic field signal with known amplitude and shape at a measurement point; a magneto-optic probe (100) for detecting a magnetic field signal of the measuring point, converting the magnetic field signal into an optical signal, and transmitting to a power supply and signal processing module (400) the optical signal sent by the magneto-optic probe; the power supply and signal processing module (400) for transmitting laser light, and converting the optical signal into an electrical signal after receiving it, and demodulating and analyzing the electric signal to acquire the magnetic field information and/or the current information of the measuring point.

  • Patent number: 8773119
    Abstract: A system for fiber DC magneto-optic detection and method thereof are provided. The system comprises a power supply and signal processing module (400), an optical fiber device (200), a magneto-optic probe (100) and a reference device (300). The reference device (300) is mounted in the system, and the measured signal can be corrected via a reference magnetic field pulse signal generated by the reference device (300) so as to eliminate the influence that the environmental factors caused on the measurement, and to obtain accurate measurement data, thus improving measurement accuracy of the system.
