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 conditions 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 control system is operably coupled to the fiber harness such that a signal indicative of scattered light associated with the node is transmitted to the control system. The control system analyzes the signal associated with the node in one or more of a frequency domain, time-frequency domain, time domain, and spatial domain, to determine at least one of a presence and magnitude of the condition within the predetermined area.
(FR) Cette invention concerne un système de détection conçu pour mesurer une ou plusieurs conditions à l'intérieur d'une zone prédéterminée, comprenant un faisceau de fibres ayant au moins un câble à fibre optique pour transmettre de la lumière. Le/les câble(s) à fibre optique définit/définissent un nœud conçu pour mesurer la/les condition(s). Un système de commande est fonctionnellement couplé au faisceau de fibres de telle sorte qu'un signal représentant la lumière diffuse associée au nœud est transmis au système de commande. Le système de commande analyse le signal associé au nœud dans un ou plusieurs domaines parmi le domaine fréquentiel, le domaine temps-fréquence, le domaine temporel et le domaine spatial, pour déterminer au moins l'une d'une présence et d'une amplitude de la condition dans la zone prédéterminée.
