The distributed fiber optic temperature sensing system can continuously measure the temperature along the fiber optic cable, with a measurement distance of several thousand meters and a spatial positioning accuracy of meters. It can perform uninterrupted automatic measurement and is particularly suitable for applications that require large-scale measurement. The traditional method for measuring temperature in distributed fiber optic temperature sensing systems is to use Stokes light to demodulate anti Stokes light, that is, to obtain the intensity ratio of anti Stokes light to Stokes light, and then compensate for the attenuation of the intensity ratio signal.

Distributed fiber optic temperature measurement technology is widely used in temperature measurement and monitoring in hazardous areas, important areas, pressure vessel surface temperature measurement and monitoring, large-scale and large-scale temperature measurement and monitoring, as well as temperature measurement and monitoring in the transportation field. Distributed fiber optic temperature measurement is widely used in temperature monitoring and fire alarm of facilities such as power, petrochemical, transportation, buildings, and water conservancy;
