Abstract

See full text

A display includes an optical waveguide with opposing front and back faces, an injection optic, and volume hologram arranged on or within the waveguide. The injection optic is configured to inject light into the waveguide at a variable injection angle, which influences the reflection angle at which the light reflects from the front and back faces on propagating through the waveguide. The hologram is configured to release, in a predetermined direction, a portion of the light from the waveguide when excited at a predetermined reflection angle.
