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: A display system aligns the location of its exit pupil with the location of a viewer's pupil by changing the location of the portion of a light source that outputs light. The light source may include an array of pixels that output light, thereby allowing an image to be displayed on the light source. The display system includes a camera that captures images of the eye and negatives of the images are displayed by the light source. In the negative image, the dark pupil of the eye is a bright spot which, when displayed by the light source, defines the exit pupil of the display system. The location of the pupil of the eye may be tracked by capturing the images of the eye, and the location of the exit pupil of the display system may be adjusted by displaying negatives of the captured images using the light source.

Abstract: Soft-imprint alignment processes for patterning liquid crystal polymer layers via contact with a reusable alignment template are described herein. An example soft-imprint alignment process includes contacting a liquid crystal polymer layer with a reusable alignment template that has a desired surface alignment pattern such that the liquid crystal molecules of the liquid crystal polymer are aligned to the surface alignment pattern via chemical, steric, or other intermolecular interaction. The patterned liquid crystal polymer layer may then be polymerized and separated from the reusable alignment template. The process can be repeated many times. The reusable alignment template may include a photo-alignment layer that does not comprise surface relief structures that correspond to the surface alignment pattern and a release layer above this photo-alignment layer. A reusable alignment template and methods of fabricating the same are also disclosed.

Abstract: A beamsplitter can include a first surface with a diffractive optical element, a second surface normal to the first surface, and a beam splitting surface arranged at an angle to the second surface that is less than 45 degrees. The beamsplitter may be configured to illuminate the entire second surface in response to an input beam at the first surface.

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: A 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 may be selected using an array of shutters that selectively regulate the entry of image light into an eye. Each opened shutter in the array provides a different intra-pupil image, and the locations of the open shutters provide the desired amount of parallax disparity between the images. In some other embodiments, the images may be formed by an emissive micro-display. Each pixel formed by the micro-display may be formed by one of a group of light emitters, which are at different locations such that the emitted light takes different paths to the eye, the different paths providing different amounts of parallax disparity.

Abstract: Disclosed is an improved diffraction structure for 3D display systems. The improved diffraction structure includes an intermediate layer that resides between a waveguide substrate and a top grating surface. The top grating surface comprises a first material that corresponds to a first refractive index value, the underlayer comprises a second material that corresponds to a second refractive index value, and the substrate comprises a third material that corresponds to a third refractive index value. According to additional embodiments, improved approaches are provided to implement deposition of imprint materials onto a substrate, which allow for very precise distribution and deposition of different imprint patterns onto any number of substrate surfaces.

Abstract: Examples of eye-imaging apparatus using diffractive optical elements are provided. For example, an optical device comprises a substrate having a proximal surface and a distal surface, a first coupling optical element disposed on one of the proximal and distal surfaces of the substrate, and a second coupling optical element disposed on one of the proximal and distal surfaces of the substrate and offset from the first coupling optical element. The first coupling optical element can be configured to deflect light at an angle to totally internally reflect (TIR) the light between the proximal and distal surfaces and toward the second coupling optical element, and the second coupling optical element can be configured to deflect at an angle out of the substrate. The eye-imaging apparatus can be used in a head-mounted display such as an augmented or virtual reality display.
