Abstract
Provided are a phase quadrature four-wavelength demodulation system and method of an optical fiber F-P cavity sensor. The phase quadrature four-wavelength demodulation system of the optical fiber F-P cavity sensor includes a flat ASE broadband light source, an optical fiber circulator, a dense wavelength division multiplexer, a photoelectric detector, and a data acquisition processing unit. The flat ASE broadband light source is connected to the optical fiber circulator, the optical fiber circulator is connected to the dense wavelength division multiplexer, the dense wavelength division multiplexer is connected to the photoelectric detector, and the photoelectric detector is connected to the data acquisition processing unit.
