基于高灵敏度光纤的检测
摘要：
一种用于测量预定区域中的一个或多个状况的存在的检测系统包括纤维束，所述纤维束具有用于传输光的至少一根光纤电缆。所述至少一根光纤电缆限定被布置来测量所述一个或多个状况的节点。所述节点被布置成使得由邻近所述节点的大气散射的光由所述光纤电缆的至少一根芯接收。可操作地连接至所述纤维束的控制系统包括用于将光传输至所述节点的光源和被配置来接收与所述节点相关联的散射光的光敏装置。所述控制系统分析对应于与所述节点相关联的所述散射光的多于一个波长的多于一个信号，以确定所述节点处的所述一个或多个状况的存在和量值中的至少一个。
摘要（英）：

A detection system for measuring the presence of one or more conditions in a predetermined area includes a fiber harness having at least one fiber optic cable for transmitting light. The at least onefiber optic cable defines a node arranged to measure the one or more conditions. The node is arranged such that light scattered by an atmosphere adjacent the node is received by at least one core of the fiber optic cable. A control system operably connected to the fiber harness includes a light source for transmitting light to the node and a light sensitive device configured to receive scattered light associated with the node. The control system analyzes more than one signal corresponding to more than one wavelength of the scattered light associated with the node to determine at least one of apresence and magnitude of the one or more conditions at the node.
