Paper Abstract

We design a new system for simultaneous distributed measurement of temperature and strain based on both spontaneous Raman and Brillouin backscattered signals. The Raman signal can determine the temperature. Although the Brillouin frequency shift is dependent on both temperature and strain of fiber, once the temperature is determined from the Raman signal, the strain can then be computed from the frequency measurement of the Brillouin signal.
