Abstract
Using hDVS techniques to detect a disturbance in a coherent Rayleigh backscatter caused by the presence of another optical signal in the fiber. The interaction can be caused by a pump pulse travelling shortly after a probe pulse and at a frequency close to that of the probe plus or minus a Brillouin frequency shift. This results in gain or attenuation of the backscatter signal. The Brillouin shift is a function of temperature and strain.
