Abstract: An example apparatus for a beam guiding device. The apparatus includes a curved lens and a beam splitter attached to the curved lens for splitting an incident light beam into a number of light beams. The apparatus may also include a coupling holographic optical element (HOE) attached to the curved lens to divert the number of light beams to a holographic coupling angle. The apparatus may also include a pair of waveguide HOEs to reflect the number of light beams within the curved lens. The apparatus may also include a decoupling HOE to divert the number of light beams from a holographic coupling angle out of the curved lens.

Abstract: Disclosed herein are devices and techniques related to optical diffusers and particularly, diffusers to reduce moiré patterns in a projected image. The device may comprise an array of micro-focal elements or reflectors and a light polarization grid. The light polarization grid configured to change a polarization between portions of a light beam and the micro-focal elements of reflectors to diffuse the light beam such that portions of the light beam having a difference in polarization may meet at a point.

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.

Abstract: Holographic optical elements for augmented reality (AR) devices and methods of manufacturing and using the same are disclosed. A disclosed system includes a holographic optical element (HOE), and a first light source to direct a first beam of light toward the HOE from a first direction. The first beam of light is collimated. The disclosed system further includes a second light source to direct a second beam of light toward the HOE from a second direction. The disclosed system also includes a decollimation lens positioned between the first light source and the HOE. The decollimation lens is to decollimate the first beam of light.
