  • Publication number: 20200089014
    Abstract: An electronic device may have a display that emits image light, a waveguide, and an input coupler that couples the image light into the waveguide. Beam splitter structures may be embedded within the waveguide. The beam splitter structures may partially reflect the image light multiple times and may serve to generate replicated beams of light that are coupled out of the waveguide by an output coupler. The beam splitter structures may replicate the beams across two dimensions to provide an eye box with uniform-intensity light from the display across its area. The beam splitter structures may include stacked partially reflective beam splitter layers, sandwiched transparent substrate layers having different indices of refraction, a thick volume hologram interposed between substrate layers, or combinations of these or other structures. The reflectivity of the beam splitter structures may vary discretely or continuously across the lateral area of the waveguide.

  • Publication number: 20200057308
    Abstract: An electronic device may have a reflective display with a pixel array that generates images. The reflective display may be illuminated by an illumination system. Light from the illumination system may be reflected by the pixel array as image light. The image light may be provided to a viewer using a waveguide with diffractive input and output couplers. The illumination system may have a waveguide. The illumination system may also have a light source such as one or more light-emitting diodes. Light from the light source may be coupled into the waveguide of the illumination system by a diffractive coupler such as volume hologram that serves as an input coupler. Light from the light source may be routed to the display to illuminate the display using the waveguide in the illumination system and a diffractive coupler such as a volume hologram that serves as an output coupler.

  • Publication number: 20190285897
    Abstract: An augmented reality headset may include a reflective holographic combiner to direct light from a light engine into a user's eye while also transmitting light from the environment. The combiner and engine may be arranged to project light fields with different fields of view and resolution to match the visual acuity of the eye. The combiner may be recorded with a series of point to point holograms; one projection point interacts with multiple holograms to project light onto multiple eye box points. The engine may include a laser diode array, a distribution waveguide, scanning mirrors, and layered waveguides that perform pupil expansion and that emit wide beams of light through foveal projection points and narrower beams of light through peripheral projection points. The light engine may include focusing elements to focus the beams such that, once reflected by the holographic combiner, the light is substantially collimated.

  • Patent number: 9715214
    Abstract: A confocal rainbow holographic imaging system and hologram fabrication method. The system employs a multi-spectral light source, a multiple grating volume hologram and a dual pass illumination and imaging pathway which provide for depth sectioning of an object, coverage of the full FOV of the system, and high lateral and depth resolution. Dual matched holograms are used to provide a high image contrast ratio. A method for fabricating the holograms employ a novel combination of design tools is also provided.

  • Patent number: 9436158
    Abstract: Provided are modular volume holographic imaging system (VHIS) endoscopic systems, comprising: an endoscope attachment module having a microscope objective lens, a single or cascaded compensated relay system configured to preserve an optical wavefront for use with a single or multiplexed volume hologram to select wavefronts originating from different object depths, and a system aperture; and a handle module configured to be reversibly attachable for operative communication with the endoscope attachment module, and having a beam splitter; a relay having adjustable spacing for object space focus compensation, and a single or multiplexed volume hologram suitable in operation to select wavefronts originating from different object depths, and wherein the handle module is further configured for operative communication with an illumination source and imaging optics. Preferably, an illumination module and an imaging module are configured to be in operative, reversibly attachable communication with the handle module.
