Title (EN) DISTRIBUTED OPTICAL FIBRE SENSOR
(FR) CAPTEURS RÉPARTIS À FIBRES OPTIQUES
Abstract: front page image
(EN)The disclosure relates to distributed optical fibre sensors arranged to detect coherent Rayleigh backscatter from a sensing optical fibre disposed in an environment, and to determine an infrasonic signal in the backscatter, or to determine a change in the environment within an infrasonic frequency range from the backscatter..
(FR)La présente invention concerne des capteurs répartis à fibres optiques conçus pour détecter la rétrodiffusion cohérente de Rayleigh à partir d'une fibre optique de détection disposée dans un environnement, et pour déterminer un signal infrasonore dans la rétrodiffusion, ou pour déterminer un changement de l'environnement dans les limites d'une plage de fréquences infrasonores à partir de la rétrodiffusion.
