    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: An imaging system includes a light source configured to generate a light beam. The system also includes first and second light guiding optical elements having respective first and second entry portions, and configured to propagate at least respective first and second portions of the light beam by total internal reflection. The system further includes a light distributor having a light distributor entry portion, a first exit portion, and a second exit portion. The light distributor is configured to direct the first and second portions of the light beam toward the first and second entry portions, respectively. The light distributor entry portion and the first exit portion are aligned along a first axis. The light distributor entry portion and the second exit portion are aligned along a second axis different from the first axis.

    Abstract: Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise a spatial light modulator operatively coupled to an image source for projecting light associated with one or more frames of image data, and a variable focus element (VFE) for varying a focus of the projected light such that a first frame of image data is focused at a first depth plane, and a second frame of image data is focused at a second depth plane, and wherein a distance between the first depth plane and the second depth plane is fixed.

    Abstract: A method and system for increasing dynamic digitized wavefront resolution, i.e., the density of output beamlets, can include receiving a single collimated source light beam and producing multiple output beamlets spatially offset when out-coupled from a waveguide. The multiple output beamlets can be obtained by offsetting and replicating a collimated source light beam. Alternatively, the multiple output beamlets can be obtained by using a collimated incoming source light beam having multiple input beams with different wavelengths in the vicinity of the nominal wavelength of a particular color. The collimated incoming source light beam can be in-coupled into the eyepiece designed for the nominal wavelength. The input beams with multiple wavelengths take different paths when they undergo total internal reflection in the waveguide, which produces multiple output beamlets.

    Abstract: A method of operating an optical system includes identifying a set of angle dependent transmittance levels for light passing through pixels of a segmented dimmer exhibiting viewing angle transmittance variations for application of a same voltage to all pixels of the segmented dimmer. The method also includes determining a set of voltages to apply to pixels of the segmented dimmer. Determining the set of voltages includes using the set of angle dependent transmittance levels. The method includes applying the set of voltages to the pixels of the segmented dimmer to achieve light transmittance through the segmented dimmer corresponding to the set of angle dependent transmittance levels.
