  • Demodulation system and demodulation method of fiber-optic sensor for obtaining phase change parameters
    Patent number: 11796351
    Abstract: Some embodiments of the disclosure provide a demodulation system for obtaining phase change parameters by a fiber-optic Fabry Perot sensor. In an embodiment, the demodulation system includes a transmitting module, a fiber-optic Fabry Perot sensor, a light splitting module, a filter module, a receiving module, and a processing module. The transmitting module transmits a beam with a predetermined wavelength range. The fiber-optic Fabry Perot sensor receives the beam and forms a reflected light beam. The light splitting module is arranged between the transmitting module and the fiber-optic Fabry Perot sensor. The filter module obtains the first light beam, the second light beam, and the third light beam. The filter module has a broadband filter. The receiving module receives the first light beam, the second light beam, and the third light beam and converts them into the first signal, the second signal, and the third signal.
