Abstract
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.
