Abstract: Methods and systems for depth-based foveated rendering in a 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 the display system. A fixation point can be 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 object(s) to present is obtained, with the location information including three-dimensional position(s) of the virtual object(s). A resolution of the virtual object(s) can be adjusted based on a proximity of the location(s) of the virtual object(s) to the fixation point. The virtual object(s) are presented by the display system according to the adjusted resolution(s).

Abstract: In some implementations, an optical device includes a one-way mirror formed by a polarization selective mirror and an absorptive polarizer. The absorptive polarizer has a transmission axis aligned with the transmission axis of the reflective polarizer. The one-way mirror may be provided on the world side of a head-mounted display system. Advantageously, the one-way mirror may reflect light from the world, which provides privacy and may improve the cosmetics of the display. In some implementations, the one-way mirror may include one or more of a depolarizer and a pair of opposing waveplates to improve alignment tolerances and reduce reflections to a viewer. In some implementations, the one-way mirror may form a compact integrated structure with a dimmer for reducing light transmitted to the viewer from the world.

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 determining a fixation point of a user's eyes. Location information associated with a first virtual object to be presented to the user via a display device is obtained. A resolution-modifying parameter of the first virtual object is obtained. A particular resolution at which to render the first virtual object is identified based on the location information and the resolution-modifying parameter of the first virtual object. The particular resolution is based on a resolution distribution specifying resolutions for corresponding distances from the fixation point. The first virtual object rendered at the identified resolution is presented to the user via the display system.

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 method of fabricating a variable diameter fiber includes providing a fiber optic cable, focusing a laser beam at a predetermined location inside the fiber optic cable, and creating a damage site at the predetermined location. The method also includes focusing the laser beam at a series of additional predetermined locations inside the fiber optic cable and creating a plurality of additional damage sites at the additional predetermined locations. The damage site and the additional damage sites define a variable diameter profile. The method further includes exposing the fiber optic cable to an etchant solution, preferentially etching the damage site and the plurality of additional damage sites, and separating a portion of the fiber optic cable to release the variable diameter fiber.
