Abstract :
Based on the optical time-domain reflectometry technology and temperature effects of spontaneous Raman back-scattering, the distributed fiber optical temperature measurement system is established. The structure and working principles of the system have been discussed. A circulated demodulation method is proposed. The spatial resolution, temperature resolution and time resolution of the system have been verified through experiments.
