  • IMAGING STRUCTURE WITH EMBEDDED LIGHT SOURCES
    Publication number: 20130207964
    Abstract: In embodiments of an imaging structure with embedded light sources, an imaging structure includes a silicon backplane with a driver pad array. The embedded light sources are formed on the driver pad array in an emitter material layer, and the embedded light sources can be individually controlled at the driver pad array to generate and emit light. A conductive material layer over the embedded light sources forms a p-n junction between the emitter material layer and the conductive material layer. Micro lens optics can be positioned over the conductive material layer to direct the light that is emitted from the embedded light sources. Further, the micro lens optics may be implemented as parabolic optics to concentrate the light that is emitted from the embedded light sources.

  • LASER ILLUMINATION SCANNING
    Publication number: 20130208362
    Abstract: In embodiments of laser illumination scanning, an imaging unit includes a linear array of spatial light modulators that direct light in a direction perpendicular to an imaging scan direction. The lasers each emit the light through a diffractive optic that uniformly illuminates the spatial light modulators, and a scanning mirror then scans the spatial light modulators to generate a two-dimensional image for display. The lasers can include red, green, and blue lasers for RGB illumination of the spatial light modulators, which can be implemented as reflective liquid crystal on silicon (LCOS), transmissive LCOS, or as micro-electro-mechanical systems (MEMS) mirrors.

  • WEARABLE DISPLAY DEVICE CALIBRATION
    Publication number: 20130187943
    Abstract: In embodiments of wearable display device calibration, a first display lens system forms an image of an environment viewed through the first display lens system. A second display lens system also forms the image of the environment viewed through the second display lens system. The first display lens system emits a first reference beam and the second display lens system emits a second reference beam. The first display lens system then captures a reflection image of the first and second reference beams. The second display lens system also captures a reflection image of the first and second reference beams. An imaging application is implemented to compare the reflection images to determine a misalignment between the first and second display lens systems, and then apply an alignment adjustment to align the image of the environment formed by each of the first and second display lens systems.

  • EYEBOX ADJUSTMENT FOR INTERPUPILLARY DISTANCE
    Publication number: 20130170031
    Abstract: In embodiments of eyebox adjustment for interpupillary distance, a first optical lens receives light of an image from a display optic at a projected orientation of the light, and the first optical lens deviates the light of the image by a deviation angle from the projected orientation of the light. A second optical lens receives the light of the image from the first optical lens at the deviation angle, and the second optical lens alters the deviated light of the image back to the projected orientation of the light for viewing the image. Left and right eyeboxes align with respective left and right eyes that view the image, and a distance between the left and right eyeboxes approximately correlates to an interpupillary distance between the left and right eyes. The light of the image can be laterally shifted to increase or decrease the distance between the left and right eyeboxes.

  • REFLECTIVE ARRAY WAVEGUIDE
    Publication number: 20130163089
    Abstract: In embodiments of reflective array waveguide, a reflective array waveguide includes clear waveguide panels for see-through viewing of an environment viewed through the reflective array waveguide. The reflective array waveguide also includes reflecting waveguide panels to reflect a virtual image that is generated to appear as part of the environment. Each of the reflecting waveguide panels have a partially reflective mirror coating deposited on opposing sides, and the reflecting waveguide panels are alternated in the reflective array waveguide with the clear waveguide panels. The alternating clear and reflecting waveguide panels are angled for augmented reality imaging of the reflected virtual image as part of the environment that is viewed through the reflective array waveguide.

  • PIXEL OPACITY FOR AUGMENTED REALITY
    Publication number: 20130162673
    Abstract: In embodiments of pixel opacity for augmented reality, a display lens system includes a first display panel that displays a virtual image generated to appear as part of an environment viewed through optical lenses. A second display panel displays an environment image of the environment as viewed through the optical lenses, and the environment image includes opaque pixels that form a black silhouette of the virtual image. The display lens system also includes a beam-splitter panel to transmit light of the environment image and reflect light of the virtual image to form a composite image that appears as the virtual image displayed over the opaque pixels of the environment image.

  • INTEGRATED EYE TRACKING AND DISPLAY SYSTEM
    Publication number: 20130077049
    Abstract: Technology is provided for an integrated eye tracking and display system for a see-through, near-eye, mixed reality display device. Image data and IR illumination for eye tracking are optically coupled into a respective see-through, planar waveguide positioned to be seen through by each eye in a respective display optical system of the display device. The respective planar waveguide comprises one or more wavelength selective filters positioned to be co-axial with an optical axis of the respective display optical system. The wavelength selective filters direct IR and visible illumination out of the planar waveguide in the direction of the respective eye and direct IR reflections, including reflections from the eye, into the planar waveguide. The reflections are optically coupled out of the waveguide to an IR sensor which generates eye tracking data based on the reflections.

  • FOLDED IMAGING PATH CAMERA
    Publication number: 20120249815
    Abstract: In embodiments of a folded imaging path camera, a device includes a camera lens module that focuses an image, which is received as reflected light. An image sensor captures the image from the reflected light that is directed at the image sensor. The device also includes one or more optics that fold the reflected light of the image along an imaging path directed through the camera lens module and directed at the image sensor. The imaging path directed through the camera lens module can be approximately perpendicular to an axis along which the reflected light of the image is received via an aperture in the device. Alternatively, the imaging path directed through the camera lens module is approximately parallel to the axis along which the reflected light of the image is received via the aperture in the device.
