Title (EN) STRAIN SENSING OPTICAL CABLE WITH ACOUSTIC IMPEDANCE MATCHED LAYERS
(FR) CÂBLE OPTIQUE À DÉTECTION DE CONTRAINTE AVEC COUCHES ADAPTÉES À L'IMPÉDANCE ACOUSTIQUE
Abstract:
(EN) A vibration sensing optical fiber cable is provided. The cable includes at least one optical fiber embedded in the cable jacket such that vibrations from the environment are transmitted into the cable jacket to the optical fiber. The cable is configured in a variety of ways, including through spatial arrangement of the sensing fibers, through acoustic impedance matched materials, through internal vibration reflecting structures, and/or through acoustic lens features to enhance sensitivity of the cable for vibration detection/monitoring.
(FR) Câble à fibres optiques à détection de vibrations. Le câble comprend au moins une fibre optique incorporée dans la gaine de câble de telle sorte que des vibrations provenant de l'environnement sont transmises dans la gaine de câble jusqu'à la fibre optique. Le câble est conçu de diverses manières, y compris par l'intermédiaire d'un agencement spatial des fibres de détection, par l'intermédiaire de matériaux adaptés à l'impédance acoustique, par l'intermédiaire de structures de réflexion de vibrations internes, et/ou par l'intermédiaire d'éléments de lentilles acoustiques pour améliorer la sensibilité du câble pour la détection/surveillance de vibrations.
