January 2022: Snapshot full Stokes imager by microgrid polarization cameras and its application for industry and bio-imaging
Monthly speakers explore topics derived from Henri Poincaré’s work on optical polarization and demonstrate applications of polarization techniques. This month's title is Snapshot full Stokes imager by microgrid polarization cameras and its application for industry and bio-imaging, presented by Yukitoshi Otani.

Join the series’ chairs and moderators – Thomas A. Germer, National Institute of Standards and Technology (USA); Jessica C. Ramella-Roman, Florida International University (USA); and Tatiana Novikova, École Polytechnique (France) – and be part of the discussion.

Abstract: This paper describes a snapshot full- Stokes imager by two microgrid polarization cameras with linear micro-polarizer array which is aligned to 0, 45, 90 and 135° of azimuthal direction. A presentation highlights an imager for full Stokes parameters with achromatic retarder, achromatic non-polarizing beam splitter and two polarization cameras with calibration method for error of retarder. We demonstrate same applications of bio-imaging using a differential interferometric microscope, microplastics and some industrial applications by high-speed polarization cameras with 1 million per seconds.
