A device provides light for augmented reality vision. The device includes a display that emits light toward a beam splitter. The beam splitter reflects light from the display toward a polarization-dependent lens. The beam splitter allows world scene light to pass therethrough to the polarization-dependent lens. The polarization-dependent lens directs display light and world scene light toward a non-polarization-dependent lens positioned at an eye-ward side of the polarization-dependent lens.

An optical combiner including a waveguide prism configured to convey display light, from a display panel, from a proximal end of the waveguide prism to a distal end of the waveguide prism via total internal reflection. The optical combiner also includes an outcoupling interface positioned at the distal end of the waveguide prism on a surface of the waveguide prism that faces a user's eye. The outcoupling interface includes a plurality of polarization-dependent layers including a refractive beam-splitting convex lens to fold the light path of the display light and reduce the dimensions of a near-eye optical system implementing the optical combiner.

Optical assemblies for use in virtual and augmented reality environments are described. The optical assemblies may include lenses, filter stacks, cameras, and image projecting devices. For example, the optical assemblies may include at least one lens, a first filter stack between the at least one lens and an image projecting device, a second filter stack between the first filter stack and the image projecting device, and a camera configured to capture images of an infrared reflection of light through the at least one lens.

A near-eye display system includes a polarization waveguide having an in-coupling interface disposed proximate to a first end and an out-coupling interface disposed proximate to an opposite second end. The polarization waveguide is configured to convey light incident at the in-coupling interface to the out-coupling interface by inducing multiple changes in a polarization state of the light as the light traverses the polarization waveguide. At least a subset of the changes in polarization state induce the light to reflect within the polarization waveguide without relying on total internal reflection (TIR).

A near-eye display device reduces vergence accommodation conflict by adjusting a tilt and/or distance of a focal plane of a display panel based on scene depth statistics. For example, many three-dimensional (3D) scenes have closer objects in the lower visual field and farther objects in the upper visual field. Changing the tilt of the focal plane of the display panel to match average 3D screen depths reduces the discrepancy between vergence and accommodation distances. In some embodiments, the near-eye display device employs a fixed tilt of the display panel to match average scene depth statistics across a variety of scenes. In some embodiments, the near-eye display device dynamically adjusts the pitch and yaw of the focal plane of the display panel to match scene statistics for a given scene.

An apparatus for use with a head wearable display includes a curved eyepiece for guiding display light received at an input surface peripherally located from a viewing region and emitting the display light along an eye-ward direction in the viewing region. The curved eyepiece includes an optical combiner, an eye-ward facing surface that is concave, a world facing surface that is convex, and a curved lightguide disposed between the eye-ward facing and world facing surfaces to guide the display light via total internal reflections from the input surface to the viewing region. The optical combiner is disposed within the curved eyepiece at the viewing region to redirect the display light towards the eye-ward direction. The optical combiner includes a pattern of reflective elements separated by interstitial regions. The interstitial regions pass ambient light incident through the world facing surface such that the viewing region is partially see-through.

Techniques and mechanisms for fabricating an eyepiece from a lens blank including blank bodies that are bonded to each other. In an embodiment, the blank bodies are formed by injection molding and adhered to one another. Fabrication of the eyepiece includes variously machining the blank bodies to shape respective lens bodies of the eyepiece. One or more blocking structures are coupled to reinforce the lens blank during at least part of such machining. In another embodiment, any blocking structures that are to resist forces of a particular machining process are coupled only indirectly to one of the blank bodies.
