Abstract

Mathematical model of distributed temperature sensor based on spontaneous Raman scattering is described in this paper. The concept uses Stokes and anti-Stokes scattered signals as reference and detection signals respectively. Model is completed by experimental results coming from setup of 200 m G.652 sensing fiber tested in temperatures 3°C, 15°C, 23 °C and 30°C and 2500 m reference fiber preserved in 22°C. Parameters of the scattered signal source in used setup configuration allow to achieve distributed temperature profile with spatial resolution up to 50 m.
