Summary

This optics paper presents a full-color polarization camera system that can capture the polarization state of light across multiple wavelengths simultaneously. The technology is demonstrated for biological imaging and is noted as applicable to microplastics detection using light polarization properties.

We propose a RGB full- Stokes video imager by two RGB microgrid polarization cameras with linear micro-polarizer array which is aligned to 0, 45, 90 and 135° of azimuthal direction. It is mainly applied to calibrate retarder and non-polarizing beam splitter with wavelength dependence. A presentation highlights applying for a bio-polarization imager to demonstrate a bio-imaging using a differential interferometric microscope, microplastics and polarization properties of incents .
