Distributed Temperature Sensing (DTS) systems utilize optical fibers as linear sensors to provide continuous temperature profiles along their length. Unlike traditional point sensors, DTS offers a comprehensive view of temperature distribution, enabling the detection of hotspots and anomalies over extensive distances. This technology leverages the Raman or Brillouin scattering effects within the fiber optic cable, where laser pulses are transmitted, and the backscattered light is analyzed to determine temperature variations. Applications span diverse sectors, including pipeline monitoring, power cable management, and fire detection, where the ability to monitor temperature continuously and accurately is crucial for safety and operational efficiency.
