Abstract
A static multiview display and method of static multiview display operation provide a static multiview image using diffractive gratings to that encode pixels of the static multiview image. The static multiview display includes a light guide configured to guide plurality of guided light beams and a light source configured to provide the guided light beam plurality having the different radial directions. The static multiview display further includes a plurality of diffraction gratings configured to provide different individual directional light beams from a portion of the radially directed guided light beams. The different individual directional light beams having different intensities and directions corresponding to and representing different view pixels of the static multiview image.
