Abstract
Holographic optical elements for augmented reality (AR) devices and methods of manufacturing and using the same are disclosed. An example AR device includes a holographic optical element (HOE) including a recorded optical function, and a projector to emit light toward the HOE. The HOE reflects the light based on the optical function to produce a full image corresponding to content perceivable by a user viewing the reflected light from within an eyebox. A first portion of the content is viewable from a first location within the eyebox. A second portion of the content is viewable from a second location within the eyebox. The first portion including different content than the second portion that is non-repeating between the first and second portions.
