Phase Mode-Matching Demodulation Scheme for Interferometric Fiber-Optic Sensors

Phase Mode-Matching Demodulation Scheme for Interferometric Fiber-Optic Sensors

A novel digital demodulation scheme for an interferometric optical fiber sensor is developed, which uses only an interferometer with zero optical path difference, and has a larger dynamic range and a faster operation speed than that of a digital phase generated carrier scheme
