Low‐finesse fiber‐optic Fabry–Perot (F‐P) interferometric sensor has the advantages of high
sensitivity, anti‐electromagnetic interference, and compact size, and is one of the most …

Phase generated carrier (PGC) demodulation schemes are widely used in fiber-optic
interferometric sensors. All known PGC schemes use carrier signals to obtain in-phase and …

We propose a novel phase generated carrier (PGC) demodulation method by
simultaneously calculating the carrier phase delay (θ) and the phase modulation depth (m) …

A precision PGC demodulation for homodyne interferometer modulated with a combined
sinusoidal and triangular signal is proposed. Using a triangular signal as additional …

We propose a precision phase-generated-carrier (PGC) demodulation method with sub-
nanometer resolution that avoids nonlinear errors in a laser wavelength sinusoidal …

Traditional phase generated carrier (PGC) schemes require that the carrier phase delay be
kept zero and the phase modulation depth be maintained at a certain value; otherwise …

Phase modulation depth (C) and carrier phase delay (θ) are two critical factors for the phase
generated carrier (PGC) demodulation scheme. Traditional PGC demodulation schemes …

In a multi-channel interferometric fiber-optic sensor system using space-division multiplexing
(SDM) and phase-generated-carrier (PGC) demodulation, the phase delay and phase …

In this article, we proposed an all-fiber laser self-mixing rangefinder by using the fabricated
tunable fiber ring cavity laser with the wide-band tunable fiber Fabry–Perot filter as the …

Low noise, good consistency, and long-term stability are critical for a multi-channel fiber
optic intrusion detection system. This paper proposes a low-noise 32-channel fiber optic …
