Abstract
A sub-hogel configuration for a high-definition light field display that can be used in the design of optical device and three-dimensional light field display technology. Three-dimensional holographic pixels (hogels) composed of monochromatic sub-hogels and a designed metasurface act as a directional optical element for a light field display. The sub-hogel structure design and method is suited for an achromatic metasurface to provide directional pixels for multiple view light field colored displays.
Claims20
A method for displaying a light field comprising:
- receiving a data set comprising an integral image from a data source;
- sub-dividing the data set into a plurality of elemental images, each elemental image comprising a plurality of pixels representing a two dimensional array of angular descriptors associated with a pair of directional coordinates;
- decomposing each elemental image into a plurality of color-channel specific elemental images;
- transmitting each elemental image to a hogel, each hogel comprising a plurality of sub-pixels and partitioned into monochromatic sub-hogels comprising a plurality of monochromatic sub-pixels, wherein the color-channel specific elemental images is are sent to a same color monochromatic sub-hogel;
- and
- generating a light field.
