  • Publication number: 20170097507
    Abstract: A display subsystem for a virtual image generation system comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted as a fixed-free flexible cantilever. The drive assembly is configured for displacing a distal end of the optical fiber about a fulcrum in accordance with a scan pattern, such that the emitted light diverges from a longitudinal axis coincident with the fulcrum. The display subsystem further comprises an optical modulation apparatus configured for converging the light from the optical fiber towards the longitudinal axis, and an optical waveguide input apparatus configured for directing the light from the optical modulation apparatus down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to an end user.

  • Publication number: 20170097506
    Abstract: A display subsystem for a virtual image generation system for use by an end user comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a collimation element mounted to a distal end of the optical fiber for collimating light from the optical fiber. The virtual image generation system further comprises a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the distal end of the optical fiber, along with the collimation element, in accordance with a scan pattern. The virtual image generation system further comprises an optical waveguide input apparatus configured for directing the collimated light from the collimation element down the planar waveguide apparatus, such that the planar waveguide apparatus displays image frames to the end user.

  • Publication number: 20160286204
    Abstract: An approach for projecting light may be implemented using a acousto-optical depth switch that uses surface acoustic waves produced along a substrate to guide image light to different areas. The surface acoustic waves may be generated on a substrate using a transducer. Surface acoustic waves of different frequencies can guide image light onto different optical elements at different physical positions. The optical elements may be configured to show objects in an image at different distances from a viewer.

  • Publication number: 20150346495
    Abstract: Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a spatial light modulator operatively coupled to an image source for projecting light associated with one or more frames of image data, and a variable focus element (VFE) for varying a focus of the projected light such that a first frame of image data is focused at a first depth plane, and a second frame of image data is focused at a second depth plane, and wherein a distance between the first depth plane and the second depth plane is fixed.
