Abstract: A display method and system are disclosed for virtual/augmented reality. The method includes the steps of generating an image by a projection engine and projecting light rays defining the image onto a diffuser holographic optical element (DHOE) located between an observer and a concave mirror element, where a concave surface of the concave mirror element faces the observer. The light rays are projected onto the DHOE at a reference angle that causes the light rays to be diffused to the concave surface of the concave mirror element and the diffused light rays are reflected back to the observer such that the observer perceives a virtual image that appears to the observer at a position behind the concave mirror element and further from the observer than the concave mirror element.

Abstract: Virtual reality (VR) displays are computer displays that present images or video in a manner that simulates a real experience for the viewer. In many cases, VR displays are implemented as head-mounted displays (HMDs) which provide a display in the line of sight of the user. Because current HMDs are composed of a display panel and magnifying lens with a gap therebetween, proper functioning of the HMDs limits their design to a box-like form factor, thereby negatively impacting both comfort and aesthetics. The present disclosure provides a different configuration for a VR display which allows for improved comfort and aesthetics, including specifically at least one coherent light source, at least one pupil replicating waveguide coupled to the at least one coherent light source to receive light therefrom, and at least one spatial light modulator coupled to the at least one pupil replicating waveguide to modulate the light.

Abstract: A method, computer readable medium, and system are disclosed for generating foveal images. The method includes the steps of redirecting first light rays towards an eye, where the first light rays are redirected by an optical combiner and produce a peripheral image and generating second light rays by a light engine. The second light rays are redirected towards the eye, where the second light rays intersect a first region of the optical combiner and converge at a nodal point within the eye and produce an inset foveal image positioned within at least a portion of the peripheral image. An origin of the second light rays is offset to intersect a second region of the optical combiner in response to a change in a gaze direction of the eye.

Abstract: A method for rendering a light field comprises projecting rays from a viewpoint positioned at a first side of a spatial light modulator (SLM) to a clipping plane positioned at an opposing side of the SLM to form an elemental view frustum within a three-dimensional scene and rendering objects within the elemental view frustum to generate components of a first elemental image for the first elemental region. The SLM may include a tiled array of non-overlapping elemental regions and a top edge and a bottom edge of a first elemental region of the non-overlapping elemental regions are intersected by the rays to form the elemental view frustum. Furthermore, the light field may include the first elemental image and additional elemental images corresponding to the array of elemental regions and each one of the additional elemental images is rendered using an additional elemental view frustum.
