Remote Speckle-Based Measurements of Backward Brillouin Acoustic Vibrations in Optical Fibers
We propose a novel technique for measurements of Brillouin acoustic vibrations based on temporal tracking of back-reflected speckle patterns. The proposed method holds the potential to enhance some of the limiting factors in Brillouin frequency measurements while yielding increased spatial resolutio...
