Polarization fading mitigation in distributed acoustic sensors based on a high-speed polarization rotator

Dataset support paper "Polarization fading mitigation in distributed acoustic sensors based on a high-speed polarization rotator" in Optics Letters A distributed optical fiber acoustic sensor based on interferometric demodulation technique with no polarization fading is demonstrated. A polarization diversity scheme based on high-speed polarization rotator is used to eliminate signal fading due to polarization mismatch in the Rayleigh backscattered signal between adjacent points on the sensing fiber. This technique yields a spatially uniform response to the applied strain. The sensor exhibited a spatial and strain resolutions of <4 m and <7 nε, respectively
