Abstract
A dynamic Brillouin fiber sensor that is immune to fluctuations in the power, frequency, or polarizing state of the pump and probe beams is described herein. A new measurand that combines information from the complex Stokes and anti-Stokes interactions is provided to extract the absolute Brillouin frequency shift while rejecting the majority of noise sources that may limit the performance of current slope-assisted Brillouin optical time domain analysis systems.
