Abstract: A near-eye display system includes an optical system facing a display panel. The optical system includes an input filter, and output filter, and a variable-power catadioptric lens assembly disposed between the input and output filters. The input and output filters are configured, along with the catadioptric lens assembly to fold a path of display light from the display panel to a user's eye. The catadioptric lens assembly includes two or more lens elements disposed along an optical axis, each lens element having at least one surface with a freeform curvature. One of the lens elements is configured to be laterally translated relative to the other lens elements so as to change an optical power of the catadioptric lens assembly.

Abstract: 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.

Abstract: 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.

Abstract: Systems and apparatus are described for a head-mounted display apparatus comprising at least one optical assembly. Each optical assembly may include a first curved lens including a first surface and a second surface, a second curved lens including a third surface and a fourth surface, the third surface being concave and including a beam splitter layer, the second curved lens being disposed between the first curved lens and an input filter assembly, and a display panel adapted to receive image content from an image projecting device and transmit the image content through the at least one optical assembly. The third surface of the second curved lens may have a radius of curvature that is larger than a radius of curvature of the second surface of the first curved lens.

Abstract: 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).
