Abstract: Illuminations systems that separate different colors into laterally displaced beams may be used to direct different color image content into an eyepiece for displaying images in the eye. Such an eyepiece may be used, for example, for an augmented reality head mounted display. Illumination systems may be provided that utilize one or more waveguides to direct light from a light source towards a spatial light modulator. Light from the spatial light modulator may be directed towards an eyepiece. Some aspects of the invention provide for light of different colors to be outcoupled at different angles from the one or more waveguides and directed along different beam paths.

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 augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity. Advantageously, the wavefront divergence, and the accommodation cue provided to the eye of the user, may be varied by appropriate selection of parallax disparity, which may be set by selecting the amount of spatial separation between the locations of light output.

Abstract: An augmented reality display system. The system can include a first eyepiece waveguide with a first input coupling grating (ICG) region. The first ICG region can receive a set of input beams of light corresponding to an input image having a corresponding field of view (FOV), and can in-couple a first subset of the input beams. The first subset of input beams can correspond to a first sub-portion of the FOV. The system can also include a second eyepiece waveguide with a second ICG region. The second ICG region can receive and in-couple at least a second subset of the input beams. The second subset of the input beams can correspond to a second sub-portion of the FOV. The first and second sub-portions of the FOV can be at least partially different but together include the complete FOV of the input image.

Abstract: An imaging system includes a light source configured to produce a plurality of spatially separated light beams. The system also includes an injection optical system configured to modify the plurality of beams, such that respective pupils formed by beams of the plurality exiting from the injection optical system are spatially separated from each other. The system further includes a light-guiding optical element having an in-coupling grating configured to admit a first beam of the plurality into the light-guiding optical element while excluding a second beam of the plurality from the light-guiding optical element, such that the first beam propagates by substantially total internal reflection through the light-guiding optical element.

Abstract: An example system for molding a photocurable material into a planar object includes a first mold structure having a first mold surface, a second mold structure having a second mold surface, and one or more protrusions disposed along at least one of the first mold surface or the second mold surface. During operation, the system is configured to position the first and second mold structures such that the first and second mold surfaces face each other with the one or more protrusions contacting the opposite mold surface, and a volume having a total thickness variation (TTV) of 500 nm or less is defined between the first and second mold surfaces. The system is further configured to receive the photocurable material in the volume, and direct radiation at the one or more wavelengths into the volume.

Abstract: Architectures are provided for selectively incoupling one or more streams of light from a multiplexed light stream into a waveguide. The multiplexed light stream can have light with different characteristics (e.g., different wavelengths and/or different polarizations). The waveguide can comprise in-coupling elements that can selectively couple one or more streams of light from the multiplexed light stream into the waveguide while transmitting one or more other streams of light from the multiplexed light stream.
