The timeliness and accuracy of detection technology is directly related to the safety of people's lives and property. In the application of this technology, temperature is a physical quantity that must to be focused on. Compared with other temperature measurement technologies, Raman distributed optical fiber sensors have the advantages of corrosion resistance, strong resistance to electromagnetic interference, small size of the system, low maintenance and cost, so they are widely used in pipeline leakage detection, high rock cable overload detection, warehouse fire detection and other situations.
