Fiber-optic interferometric sensing is a very attractive approach for creating lightweight, high-
sensitive, and fully passive fiber-optic hydrophone arrays. In this paper, results of sea trials …

Fiber-optic interferometric sensors (FOISs) are widely used in seismometers, hydrophones,
and gyroscopes. The arctangent approach of phase-generated carrier (PGC-Arctan) …

In this paper, we report the design and development of a fiber optic hydrophone for
underwater applications. The sensing configuration is based on a Michelson interferometer …

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

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 generated carrier (PGC) demodulation technology has been widely used in fiber-
optic interferometric sensors while nonlinearity is always accompanying with the scheme …

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