Snapshot polarimeter fundus camera [PDF]
Applied Optics, 2009 A snapshot imaging polarimeter utilizing Savart plates is integrated into a fundus camera for retinal imaging. Acquired retinal images can be processed to reconstruct Stokes vector images, giving insight into the polarization properties of the retina. Results for images from a normal healthy retina and retinas with pathology are examined and compared.

An All-Dielectric Metasurface Polarimeter [PDF]
ACS Photonics, 2022 We demonstrate an all-dielectric meta-polarimeter with a single unit-cell design capable of direct measurement of any arbitrary polarization states, achieving a polarization-measurement fidelity of 99 ± 1%. This holds promise for ultra-compact polarization imaging and quantum state tomography.

High speed partial Stokes imaging using a ferroelectric liquid crystal modulator [PDF]
Journal of the European Optical Society-Rapid Publications, 2008 This paper describes the implementation of an imaging polarimeter using a single ferroelectric liquid crystal light modulator. It provides partial imaging Stokes information at 234 Hz, much faster than polarimeters using nematic light modulators.
