DOI: 10.1109/jlt.2024.3521040

Abstract: In this article, we propose a modified phase generated carrier (PGC) demodulation scheme combining dual modulation techniques for acoustic wave detection by long-cavity Fabry–Perot sensors. The scheme is effective in solving the weakness of the… read more here.

DOI: 10.1109/jsen.2023.3336331

Abstract: The quadrature signals in the phase generated carrier (PGC) demodulation scheme inevitably introduce nonlinear errors degrading the robustness. A highly robust PGC demodulation scheme based on a Lissajous figure judging module and a renormalization ellipse… read more here.

DOI: 10.1364/ao.440339

Abstract: The phase generated carrier (PGC) algorithm is often used in the demodulation of interference signals in optical fiber sensors for its high sensitivity, good linearity, and large dynamic range. However, the PGC demodulation method is… read more here.

DOI: 10.1364/ao.459267

Abstract: In this paper, an improved phase generated carrier (PGC) demodulation algorithm based on frequency mixing and division difference is proposed. The effects of phase modulation depth variation and light intensity disturbance of the light source… read more here.
