DTS distributed fiber optic temperature measurement system: a sensing system that can monitor the temperature measurement points of multiple objects and measure the spatial temperature field distribution online. It is a distributed, continuous, and functional fiber optic temperature measurement system. In the system, optical fibers not only play a photosensitive role, but also guide light. By utilizing the temperature effect of backward Raman scattering in optical fibers, real-time measurement of the temperature field in which the fiber is located can be achieved; The use of optical time-domain reflection technology (OTOR) can accurately locate measurement points. A professional fiber optic temperature measurement manufacturer in China has independently developed multiple fiber optic temperature measurement systems and has a leading invention patent in China.
