Abstract: As the most common member of the underground pipeline, optical cable has already spread throughout the urban region. By combining the distributed acoustic sensing (DAS)
Therefore, when the differential phase-OTDR is adopted to accurately position the vibration position of the optical cable, the problem of the vibration positioning blind area of the...
In this paper, a simple and low cost optical fiber sensing technology by using loop transmission polarization detection and cross-correlation algorithm for long distance vibration
To solve this problem, we propose a strain and vibration event positioning system by employing correlated positioning techniques, pulse coding techniques, a broadband light source, and
