Title: HIGH SENSITIVITY FIBER OPTIC BASED DETECTION
Abstract:
A control system of a detection system for measuring one or more conditions within a predetermined area includes a control unit having at least one processor for implementing an algorithm and a fiber harness having at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining at least one node arranged to measure the one or more conditions. A sensor is operably coupled to the at least one node, wherein the sensor receives scattered light associated with the at least one node and generates signals corresponding to the scattered light. A switch is operably coupled to the sensor and to the control unit. The switch selectively provides signals from the sensor to the control unit for processing to determine at least one of a presence and magnitude of the condition within the predetermined area.
