Abstract
A sub-hogel configuration for a high-definition light field display. Also described is an optical device and three-dimensional light field display technology and more particularly, three-dimensional holographic pixels (hogels) composed of monochromatic sub-hogels and a designed metasurface acting as a directional optical element for a light field display. The described sub-hogel structure design and method is suited for an achromatic metasurface to provide directional pixels for multiple view light field coloured displays.
