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: 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.

Abstract: An image display system includes an optical subsystem configured to emit a first light beam and a second light beam, wherein the first light beam illuminates a first portion of a composite field of view and the second beam illuminates a second portion of the composite field of view. A scanning mirror is positioned to intercept and reflect the first light beam and the second light beam. The system also has a waveguide with at least one input coupling optical element for receiving the first light beam and the second light beam into the waveguide. The waveguide also has an output coupling optical element for projecting a plurality of output light beams derived from the first light beam and the second light beam from the waveguide to illuminate the composite field of view.

Abstract: An example head-mounted display device includes a light projector, an optical assembly arranged to direct light from a light projector to a user, and an actuator module. The optical assembly includes a variable focus lens assembly including a rigid refractive component, a shaper ring defining an aperture, and a flexible lens membrane between the shaper ring and the rigid refractive component and covering the aperture. The refractive component, the shaper ring, and the lens membrane are arranged along an axis. The refractive component and the lens membrane define a chamber containing a volume of fluid. The actuator module is configured to adjust an optical power of the variable focus lens by moving the shaper ring relative to the refractive component along the axis, such that a curvature of the lens membrane in the aperture is modified.
