  • Patent number: 12007573
    Abstract: An augmented reality (AR) device is described with a display system configured to adjust an apparent distance between a user of the AR device and virtual content presented by the AR device. The AR device includes a first tunable lens that change shape in order to affect the position of the virtual content. Distortion of real-world content on account of the changes made to the first tunable lens is prevented by a second tunable lens that changes shape to stay substantially complementary to the optical configuration of the first tunable lens. In this way, the virtual content can be positioned at almost any distance relative to the user without degrading the view of the outside world or adding extensive bulk to the AR device. The augmented reality device can also include tunable lenses for expanding a field of view of the augmented reality device.

  • Patent number: 11977230
    Abstract: A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.

  • Publication number: 20240126090
    Abstract: Head mounted display systems configured to project light to an eye of a user to display augmented reality image content in a vision field of the user are disclosed. In embodiments, the system includes a frame configured to be supported on a head of the user, an image projector configured to project images into the user's eye, a camera coupled to the frame, a waveguide optically coupled to the camera, an optical coupling optical element me, an out-coupling element configured to direct light emitted from the waveguide to the camera, and a first light source configured to direct light to the user's eye through the waveguide.

  • Publication number: 20240069334
    Abstract: A display system aligns the location of its exit pupil with the location of a viewer's pupil by changing the location of the portion of a light source that outputs light. The light source may include an array of pixels that output light, thereby allowing an image to be displayed on the light source. The display system includes a camera that captures images of the eye and negatives of the images are displayed by the light source. In the negative image, the dark pupil of the eye is a bright spot which, when displayed by the light source, defines the exit pupil of the display system. The location of the pupil of the eye may be tracked by capturing the images of the eye, and the location of the exit pupil of the display system may be adjusted by displaying negatives of the captured images using the light source.

  • Publication number: 20240045215
    Abstract: An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity.

In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity may be selected using an array of shutters that selectively regulate the entry of image light into an eye. Each opened shutter in the array provides a different intra-pupil image, and the locations of the open shutters provide the desired amount of parallax disparity between the images. In some other embodiments, the images may be formed by an emissive micro-display.

  • Publication number: 20230417986
    Abstract: An eyepiece for an augmented reality display system. The eyepiece can include a waveguide substrate. The waveguide substrate can include an input coupler grating (ICG), an orthogonal pupil expander (OPE) grating, a spreader grating, and an exit pupil expander (EPE) grating. The ICG can couple at least one input light beam into at least a first guided light beam that propagates inside the waveguide substrate. The OPE grating can divide the first guided light beam into a plurality of parallel, spaced-apart light beams. The spreader grating can receive the light beams from the OPE grating and spread their distribution. The spreader grating can include diffractive features oriented at approximately 90° to diffractive features of the OPE grating. The EPE grating can re-direct the light beams from the first OPE grating and the first spreader grating such that they exit the waveguide substrate.

  • Publication number: 20230408823
    Abstract: Architectures are provided for selectively outputting light for forming images, the light having different wavelengths and being outputted with low levels of crosstalk. In some embodiments, light is incoupled into a waveguide and deflected to propagate in different directions, depending on wavelength. The incoupled light then outcoupled by outcoupling optical elements that outcouple light based on the direction of propagation of the light. In some other embodiments, color filters are between a waveguide and outcoupling elements. The color filters limit the wavelengths of light that interact with and are outcoupled by the outcoupling elements. In yet other embodiments, a different waveguide is provided for each range of wavelengths to be outputted. Incoupling optical elements selectively incouple light of the appropriate range of wavelengths into a corresponding waveguide, from which the light is outcoupled.
