Phase-sensitive optical time-domain reflectometry with pulse mode EDFA: Probe pulse preparation
A. O. Chernutsky, A. A. Zhirnov, A. K. Fedorov +6
Probe pulse preparation techniques play an important role for fiber-optic sensing. In this work, we investigate a setup for distributed sensors based on phase-sensitive optical tim…
Influence of the laser frequency drift in phase-sensitive optical time-domain reflectometry
A. A. Zhirnov, K. V. Stepanov, A. O. Chernutsky +5
The influence of the laser frequency drift on the operation of phase-sensitive optical time-domain reflectometry (-OTDR) systems is considered. Theoretical results based on a ne…
Towards events recognition in a distributed fiber-optic sensor system: Kolmogorov-Zurbenko filtering
Aleksey Fedorov, Maxim Anufriev, Andrey Zhirnov +4
The paper is about de-noising procedures aimed on events recognition in signals from a distributed fiber-optic vibration sensor system based on the phase-sensitive optical time-dom…
Gaussian mixture model for event recognition in optical time-domain reflectometry based sensing systems
Aleksey Fedorov, Maxim Anufriev, Andrey Zhirnov +5
We propose a novel approach to the recognition of particular classes of non-conventional events in signals from phase-sensitive optical time-domain-reflectometry-based sensors. Our…
