Title (EN) HIGH SENSITIVITY FIBER OPTIC BASED DETECTION
(FR) DÉTECTION À BASE DE FIBRES OPTIQUES À HAUTE SENSIBILITÉ
Abstract:
(EN) A detection system for measuring one or more condition within a predetermined area includes a fiber harness having at least one fiber optic cable for transmitting light. The at least one fiber optic cable defines a node arranged to measure the one or more conditions. A light source is coupled to the at least one fiber optic cable for emitting a modulated light to the node. The modulated light is transmitted into the predetermined area. A light sensitive device is coupled to the at least one fiber optic cable for receiving scattered light associated with the node. A control unit is operably coupled to the light source and to the light sensitive device to determine at least one of a presence and magnitude of the one or more conditions within the predetermined area.
(FR) L'invention concerne un système de détection permettant de mesurer une ou plusieurs conditions à l'intérieur d'une zone prédéfinie, comprenant un faisceau de fibres comportant au moins un câble à fibres optiques servant à transmettre de la lumière. Ledit câble à fibres optiques définit un nœud conçu pour mesurer la ou les conditions. Une source de lumière est couplée audit câble à fibres optiques de façon à émettre une lumière modulée vers le nœud. La lumière modulée est transmise dans la zone prédéfinie. Un dispositif sensible à la lumière est couplé audit câble à fibres optiques de façon à recevoir la lumière diffusée associée au nœud. Une unité de commande est couplée de manière fonctionnelle à la source de lumière et au dispositif sensible à la lumière de façon à déterminer une présence et/ou une amplitude de la ou des conditions à l'intérieur de la zone prédéfinie.
