Digitalized Polarization Fading Suppression and Phase Demodulation Scheme of Phase-Sensitive Optical Time-Domain Reflectometry Based on Polarization Diversity Virtual Coherence

Digitalized Polarization Fading Suppression and Phase Demodulation Scheme of Phase-Sensitive Optical Time-Domain Reflectometry Based on Polarization Diversity Virtual Coherence

In this paper, a digitalized polarization fading suppression and phase demodulation technique for a phase-sensitive optical time-domain reflectometry (φ-OTDR) sensing system utilizing polarization diversity virtual coherence is proposed, in which virtual cross-coherence between the polarization dive...
