In the distributed optical fiber sensing (DOFS) domain, simultaneous measurement of vibration and temperature/strain based on Rayleigh scattering and Brillouin scattering in fiber could have wide applications. However, there are certain challenges fo

Characterizing and real-time compensating the time-skew and phase-mismatch of the in-phase and quadrature (I/Q) signals, for phase-sensitive optical time-domain reflectometry (Φ-OTDR) with heterodyne detection, are the aims of this paper. After ampl

In this paper, the quadrature amplitude imbalance which may consist in I/Q demodulated phase-sensitive optical time-domain reflectometry ( $\Phi $ -OTDR) is analyzed, which may happen in both ac and dc components of received signals. Based on the ana

A repeater-less Brillouin optical time-domain analyzer (BOTDA) with 157.68km sensing range is demonstrated, using the combination of random fiber laser Raman pumping and low-noise laser-diode-Raman pumping. With optical pulse coding (OPC) and Non Loc

We propose a new phase demodulation scheme for phase-sensitive Optical Time-Domain Reflectometry (Φ-OTDR). The technique is based on I/Q demodulation and homodyne detection using a 90° optical hybrid. Both the theoretical analysis and the experimen

Due to the similarity of Brillouin optical time domain analyzer (BOTDA) signals, image denoising could be utilized to remove the noise. However, the performance can be much degraded due to inaccurate noise level estimation. By numerical and experimen

We demonstrate a novel distributed acoustic sensing (DAS) system based on phase-sensitive optical time-domain reflectometry (Φ-OTDR). Both the phase and the amplitude of the Rayleigh scattering (RS) light can be demodulated in real-time. The techniq
