    Abstract: An eyepiece for projecting an image light field to an eye of a viewer for forming an image of virtual content includes a waveguide, a light source configured to deliver a light beam to be incident on the waveguide, a controller coupled to the light source and configured to modulate an intensity of the light beam in a plurality of time slots, a dynamic input coupling grating (ICG) configured to, for each time slot, diffract a respective portion of the light beam into the waveguide at a respective total internal reflection (TIR) angle corresponding to a respective field angle, and an outcoupling diffractive optical element (DOE) configured to diffract each respective portion of the light beam out of the waveguide toward the eye at the respective field angle, thereby projecting the light field to the eye of the viewer.

    Abstract: In some embodiments, an augmented reality system includes at least one waveguide that is configured to receive and redirect light toward a user, and is further configured to allow ambient light from an environment of the user to pass therethrough toward the user. The augmented reality system also includes a first adaptive lens assembly positioned between the at least one waveguide and the environment, a second adaptive lens assembly positioned between the at least one waveguide and the user, and at least one processor operatively coupled to the first and second adaptive lens assemblies. Each lens assembly of the augmented reality system is selectively switchable between at least two different states in which the respective lens assembly is configured to impart at least two different optical powers to light passing therethrough, respectively. The at least one processor is configured to cause the first and second adaptive lens assemblies to synchronously switch between different states in a manner such that the first and second adaptive lens assemblies impart a substantially constant net optical power to ambient light from the environment passing therethrough.

    Abstract: Head-mounted virtual and augmented reality display systems include a light projector with one or more emissive micro-displays having a first resolution and a pixel pitch. The projector outputs light forming frames of virtual content having at least a portion associated with a second resolution greater than the first resolution. The projector outputs light forming a first subframe of the rendered frame at the first resolution, and parts of the projector are shifted using actuators, such that physical positions of light output for individual pixels occupy gaps between the old locations of light output for individual pixels. The projector then outputs light forming a second subframe of the rendered frame. The first and second subframes are outputted within the flicker fusion threshold. Advantageously, an emissive micro-display (e.g., micro-LED display) having a low resolution can form a frame having a higher resolution by using the same light emitters to function as multiple pixels of that frame.
