Abstract
This presentation reports a snapshot polarimetry system, capable of measuring a Stokes vector distribution within a millisecond timescale. The proposed system measures at a perpendicular backscattering angle and features a polarization state analyzer with no moving parts, comprised of a pair of quarter waveplates and pixel polarization cameras. An additional novel design aspect of the system is its capability to register polarization speckle. Polarization speckle contains both polarization and phase information that is not available from conventional techniques. The device’s acquisition speed and small form factor enable future studies of polarization speckle for biomedical applications.
