Phase noise effects on phase-sensitive OTDR sensors using optical pulse compression
(IEEE, 2021)
info:eu-repo/semantics/article,
We introduce a detailed theoretical, numerical, and experimental study of the effects of laser's phase noise on the performance of phase-sensitive optical time-domain reflectometry (-OTDR) sensors that use optical pulse ...
Long-range traffic monitoring based on pulse-compression distributed acoustic sensing and advanced vehicle tracking and classification algorithm
(MDPI, 2023)
Artículo / Artikulua,
We introduce a novel long-range traffic monitoring system for vehicle detection, tracking, and classification based on fiber-optic distributed acoustic sensing (DAS). High resolution and long range are provided by the use ...
Compensation of phase noise impairments in distributed acoustic sensors based on optical pulse compression time-domain reflectometry
(IEEE, 2023)
info:eu-repo/semantics/article,
We introduce a method to compensate for the deleterious effects of the phase noise of the laser source on long-range distributed acoustic sensors (DAS) that implement optical pulse compression (OPC). Pulse compression can ...
