Journal ArticleDOI
Single-shot distributed temperature and strain tracking using direct detection phase-sensitive OTDR with chirped pulses.
Juan Pastor-Graells,Hugo F. Martins,Andres Garcia-Ruiz,Sonia Martin-Lopez,Miguel Gonzalez-Herraez +4 more
TL;DR: It is demonstrated that by acting on the phase profile of the optical pulses, it is possible to introduce important conceptual and practical changes to the traditional ΦOTDR operation, thus opening a door for new possibilities which are yet to be explored.
Journal ArticleDOI
Distributed sensing of microseisms and teleseisms with submarine dark fibers.
Ethan Williams,Maria R. Fernandez-Ruiz,Regina Magalhães,Roel Vanthillo,Zhongwen Zhan,Miguel Gonzalez-Herraez,Hugo F. Martins +6 more
TL;DR: Observations of microseism, local surface gravity waves, and a teleseismic earthquake along a 4192-sensor ocean-bottom DAS array offshore Belgium are reported, suggesting significant potential of DAS in next-generation submarine seismic networks.
Journal ArticleDOI
Coherent Noise Reduction in High Visibility Phase-Sensitive Optical Time Domain Reflectometer for Distributed Sensing of Ultrasonic Waves
Hugo F. Martins,Sonia Martin-Lopez,Pedro Corredera,Massimo L. Filograno,Orlando Frazão,Miguel Gonzalez-Herraez +5 more
TL;DR: In this paper, the authors present an experimental and theoretical description of a high-visibility phase-sensitive optical time domain reflectometry (φOTDR) and its performance when used for ultrasonic vibration measurements.
Journal ArticleDOI
Optical Current Sensors for High Power Systems: A Review
Ricardo M. Silva,Hugo F. Martins,I. M. Nascimento,José Baptista,Antonio B. Lobo Ribeiro,Jose Luis Santos,Pedro A. S. Jorge,Orlando Frazão +7 more
TL;DR: In this article, a review of optical sensors technologies for electrical current metering in high voltage applications is presented, including fiber sensors, bulk magneto-optical sensors, piezoelectric transducers, magnetic force sensors and hybrid sensors.
Journal ArticleDOI
Toward Prevention of Pipeline Integrity Threats Using a Smart Fiber-Optic Surveillance System
Javier Tejedor,Hugo F. Martins,Daniel Piote,Javier Macias-Guarasa,Juan Pastor-Graells,Sonia Martin-Lopez,Pedro Corredera Guillen,Filip De Smet,Willy Postvoll,Miguel Gonzalez-Herraez +9 more
TL;DR: The results obtained are promising given the complexity of the task and open the path to future improvements toward fully functional pipeline threat detection systems operating in real conditions.
