Non-linear angular momentum metasurface

Abstract:

This document relates to an optical device using waveguide that can enable propagation of large field of view images by use of metasurfaces, without the necessity of increasing the reflective index associated with the waveguide. The metasurfaces can further provide image distortion correction to images to account for possible distortion introduced by an optical assembly. The metasurfaces can also be used to create a foveated image, in order to achieve a larger field of view for the image.
