Abstract: Techniques are described for operating an optical system. In some embodiments, light associated with a world object is received at the optical system. Virtual image light is projected onto an eyepiece of the optical system. A portion of a system field of view of the optical system to be at least partially dimmed is determined based on information detected by the optical system. A plurality of spatially-resolved dimming values for the portion of the system field of view may be determined based on the detected information. The detected information may include light information, gaze information, and/or image information. A dimmer of the optical system may be adjusted to reduce an intensity of light associated with the world object in the portion of the system field of view according to the plurality of dimming values.

Abstract: A wearable display system includes a light projection system having one or more emissive micro-displays, e.g., micro-LED displays. The light projection system projects time-multiplexed left-eye and right-eye images, which pass through an optical router having a polarizer and a switchable polarization rotator. The optical router is synchronized with the generation of images by the light projection system to impart a first polarization to left-eye images and a second different polarization to right-eye images. Light of the first polarization is incoupled into an eyepiece having one or more waveguides for outputting light to one of the left and right eyes, while light of the second polarization may be incoupled into another eyepiece having one or more waveguides for outputting light to the other of the left and right eyes. Each eyepiece may output incoupled light with variable amounts of wavefront divergence, to elicit different accommodation responses from the user's eyes.

Abstract: A dynamically actuable lens includes a substrate having a surface and a metasurface diffractive optical element (DOE) formed on the surface. The metasurface DOE includes a plurality of raised portions and defines a plurality of recesses between adjacent raised portions. The dynamically actuable lens also includes a movable cover overlying the metasurface DOE and comprising a hydrophilic material, a quantity of a fluid disposed on the movable cover, and a drive mechanism coupled to the movable cover. The drive mechanism is configured to move the movable cover toward the metasurface DOE to displace a portion of the quantity of the fluid into the plurality of recesses, thereby rendering the metasurface DOE in an “off” state, and move the movable cover away from the metasurface DOE, causing the portion of the quantity of the fluid retracting from the plurality of recesses, thereby rendering the metasurface DOE in an “on” state.

Abstract: A method of performing localization of a handheld device with respect to a wearable device includes capturing, by a first imaging device mounted to the handheld device, a fiducial image containing a number of fiducials affixed to the wearable device and capturing, by a second imaging device mounted to the handheld device, a world image containing one or more features surrounding the handheld device. The method also includes obtaining, by a sensor mounted to the handheld device, handheld data indicative of movement of the handheld device, determining the number of fiducials contained in the fiducial image, and updating a position and an orientation of the handheld device using at least one of the fiducial image or the world image and the handheld data.

Abstract: Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.

Abstract: Examples of a light field metrology system for use with a display are disclosed. The light field metrology may capture images of a projected light field, and determine focus depths (or lateral focus positions) for various regions of the light field using the captured images. The determined focus depths (or lateral positions) may then be compared with intended focus depths (or lateral positions), to quantify the imperfections of the display. Based on the measured imperfections, an appropriate error correction may be performed on the light field to correct for the measured imperfections. The display can be an optical display element in a head mounted display, for example, an optical display element capable of generating multiple depth planes or a light field display.
