  • Publication number: 20190101757
    Abstract: An eye tracking system includes a light guide comprising a first eye-facing surface, a second surface, a third surface, and a plurality of facets formed in the second surface. The facets reflect a portion of light incident on a user eye into the light guide, which is positioned proximate to the user eye and between the user eye and a display. A surface of a compensator may be shaped complementary to the second surface of the light guide and placed proximate to the light guide. A camera or image sensor is oriented toward the third surface of the light guide and captures an image based on internally reflected light. An IR light source may be included. The image sensor may be an IR image sensor. Based on the image, a pose of the user eye is determined. A faceted light guide assembly may include a reflective coating adjacent the facets.

  • Patent number: 10162180
    Abstract: An eyepiece for a head wearable display includes a curved lightguide component, an input coupler, and an output coupler. The curved lightguide component guides display light received at an input region peripherally located from a viewing region and emits the display light along an eye-ward direction in the viewing region. The curved lightguide component includes an eye-ward facing surface that is concave and a world facing surface that is convex. The input coupler is disposed at the input region to couple the display light into the curved lightguide component. The output coupler is disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide component. The output coupler is partially transmissive to ambient light incident through the world facing surface. The display light is guided between the input coupler and the output coupler entirely by total internal reflection.

  • Patent number: 10146054
    Abstract: An eyepiece for a head wearable display includes a curved lightguide component, a curved see-through component, an output coupler, and a prescription layer. The curved lightguide component guides display light received at an input region and releases the display light along an eye-ward direction in a viewing region. The output coupler is disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide component. The output coupler is at least partially transmissive to ambient light incident through a world-facing side such that the viewing region is see-through. The curved see-through component is mated to the world-facing side of the curved lightguide component. The prescription layer has a first side mated to an eye-facing side of the curved lightguide component and a second side having a curvature that introduces prescriptive lensing to both the ambient light and the display light.

  • Publication number: 20180252923
    Abstract: An apparatus for use with a head wearable display includes a curved eyepiece for guiding display light received at an input surface peripherally located from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes an optical combiner, an eye-ward facing surface that is concave, a world facing surface that is convex, and a curved lightguide disposed between the eye-ward facing and world facing surfaces to guide the display light via total internal reflections from the input surface to the viewing region. The optical combiner is disposed within the curved eyepiece at the viewing region to redirect the display light towards the eye-ward direction. The optical combiner includes a pattern of reflective elements separated by interstitial regions. The interstitial regions pass ambient light incident through the world facing surface such that the viewing region is partially see-through.

  • Publication number: 20180136468
    Abstract: A freeform projection display includes an optical emitter configured to output one or more wavelengths of light and an optical diffuser optically coupled to receive and disperse the one or more wavelengths of light from the optical emitter, wherein the optical diffuser has at least one radius of curvature. The freeform projection display further includes a refractive lens optically coupled to receive the one or more wavelengths of light from the optical diffuser and to project the one or more wavelengths of light. The freeform projection display further may include a light modulator disposed between the optical emitter and the optical diffuser, wherein the light modulator oscillates to project the image on the optical diffuser. An illuminated area of the optical diffuser is dimensioned so that the image produced by the light modulator fills an aperture of the refractive lens.

  • Patent number: 9964767
    Abstract: A display apparatus includes a transparent substrate having first and second sides, an array of LED micro-display panels, and an array of collimating reflectors. The LED micro-display panels are disposed within the transparent substrate between the first and second sides and oriented to emit sub-image portions of a display image towards the first side. The collimating reflectors are disposed within the transparent substrate between the first side and the array of LED micro-display panels. The collimating reflectors are aligned with the LED micro-display panels to reflect the sub-image portions back out the second side of the transparent substrate. The LED micro-display panels are offset from the collimating reflectors to expand the sub-image portions prior to reflection by the collimating reflectors.

  • Patent number: 9964769
    Abstract: Implementations are described of an eyepiece for a head wearable display. The eyepiece includes a curved lightguide for guiding display light via total internal reflection between a peripherally-located input surface and a viewing region and an output coupler disposed across the viewing region to redirect the display light towards an eyeward direction for output from the curved light guide. The output coupler has an optical axis and has a set of reflective surfaces that includes at least two individual reflective surfaces to reflect incident display light toward the eyeward direction in at least two different directions relative to the optical axis of the output coupler. Other embodiments are disclosed and claimed.

  • Patent number: 9897811
    Abstract: An apparatus for use with a head wearable display includes a curved eyepiece for guiding display light to a viewing region offset from a peripheral location and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes a curved lightguide to guide the display light, an eye-ward facing surface that is concave, a world facing surface that is convex and opposite the eye-ward facing surface, and an optical combiner disposed at the viewing region to redirect the display light towards the eye-ward direction for output from the curved lightguide. The optical combiner is partially transmissive to ambient light incident through the world facing surface such that the viewing region is see-through. In some embodiments, a prism is disposed proximate to the input surface to pre-compensate the display light for lateral chromatic aberrations resulting the curved lightguide.
