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: Very high refractive index (n>2.2) lightguide substrates enable the production of 70° field of view eyepieces with all three color primaries in a single eyepiece layer. Disclosed herein are viewing optics assembly architectures that make use of such eyepieces to reduce size and cost, simplifying manufacturing and assembly, and better-accommodating novel microdisplay designs.

Abstract: Waveguides comprising materials with refractive index greater than or equal to 1.8 and methods of patterning waveguides are disclosed. Patterned waveguides comprising materials with refractive index greater than or equal to 1.8 can be incorporated in display devices, such as, for example wearable display devices to project virtual images to a viewer. A waveguide may be transparent and may comprise a substrate comprising a first material having a first refractive index greater than about 2.0. Diffractive features may be formed, on the substrate, of a second material having a second refractive index that is lower than the first refractive index. A third material may be disposed over the diffractive features and may have a third refractive index that is higher than the second refractive index.

Abstract: Disclosed herein are systems and methods for displays, such as for a head wearable device. An example display can include an infrared illumination layer, the infrared illumination layer including a waveguide having a first face and a second face, the first face disposed opposite the second face. The illumination layer may also include an in-coupling grating disposed on the first face, the in-coupling grating configured to couple light into the waveguide to generate internally reflected light propagating in a first direction. The illumination layer may also include a plurality of out-coupling gratings disposed on at least one of the first face and the second face, the plurality of out-coupling gratings configured to receive the internally reflected light and couple the internally reflected light out of the waveguide.

Abstract: Methods and systems for qualifying a multi-layered optical stack include providing the multi-layered optical stack including a first optical layer and a second optical layer. The first optical layer includes a first pair of fiducial marks and the second optical layer includes a second pair of fiducial marks Each of the first pair are spaced laterally from each of the second pair such that the first pair and the second pair are visible through the optical stack. A first angle defined between a first reference line connecting the first pair and a global reference line is determined. A second angle defined between a second reference line connecting the second pair and the global reference line is determined. The multi-layered optical stack is qualified for use in the optical projection system based on whether a difference between the first angle and the second angle is less than a predetermined threshold.
