Abstract
A micropolarimeter is described for simultaneously extracting all Stokes parameters from incident light. The micropolarimeter includes at least one superpixel, which further includes three or more subpixels, each exact a different polarization components from the incident light. The micropolarimeter includes a first and second alignment layers and a liquid crystal layer disposed between the first and second alignment layers. The liquid crystal molecules of the liquid crystal layer are aligned in accordance with the first and second alignment layers to form the superpixel. A method is provided for manufacturing the photo-aligned liquid-crystal micropolarimeter array.
