Abstract
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.
