Research on a high-resolution distributed fiber temperature sensing system
This paper presents a high-resolution distributed fiber temperature sensing system based on spontaneous Raman scattering
which detects the density of the backscattering light and the varied temperature along the sensing fiber on the basis of the relationship between the reflected light density and temperature.In this paper
we discuss in detail the operating principle of system
set up a sensing system and perform a series of temperature sensing experiments.The results show that the system temperature resolution reaches 0.1℃ and its spatial resolution is 1 m.
