Abstract: 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.

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: The present invention relates generally to stereoscopic displays, and more particularly, but not exclusively, to stereoscopic displays with addressable focus cues.

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).

Abstract: A headset for experiencing an augmented and/or a virtual reality environment may include a housing defining an interior cavity, with optical components received in the interior cavity of the housing. A front face may be rotatably coupled to a front portion of the housing to selectively enclose the interior of the housing. A computing device including a display may be received in a slot defined between the front portion of the housing and the front face. A face pad may be removably coupled to the housing, opposite the front face, so as to enclose the optical components in the housing. A user may view an augmented/virtual reality environment displayed on the display through the optical components received in the housing. An adjustable head strap assembly may adjustably position the headset on the head of the user.

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: An optical device, such as a head mounted display, includes a display that emits light, a reflector, and a partially reflective circular polarizer (RCP) positioned between the reflector and a user's eye or eyes. The reflector can be partially reflective. The partially reflective circular polarizer, the reflector, or both, can be curved. Light from the display is reflected one or more times by the reflector. The RCP can include one or more of a quarter-wave plate (QWP), a reflective polarizer layer, a linear polarizer, a supportive substrate, and an anti-reflective film. The reflector can include a mirror coating and an anti-reflection coating.

Abstract: A lens assembly has two opposing surfaces, each surface introducing field curvature in a direction opposite of the field curvature introduced by the opposing surface, and thus the field curvatures introduced by the two surfaces at least partially cancel each other out, resulting in a net field curvature that provides for a substantially flat image plane or for an image plane with a specified curvature. The lens assembly may be implemented as a lens with two opposing Fresnel surfaces so that the field curvature in one direction introduced by one of the Fresnel surfaces is at least partially canceled out by the field curvature in the opposite direction as introduced by an opposing Fresnel surface. Alternatively, the lens assembly may be implemented as a lens with a positive continuous aspheric surface facing the user's eye and an opposing Fresnel surface facing the display panel.

Abstract: An optical system includes a first filter stack configured to convert light received from a display to a first circular polarization, a second filter stack configured to convert light received from external sources to a second circular polarization, and a third filter stack configured to reflect light having the first circular polarization and transmit light having the second circular polarization. The optical system also includes a refractive beam splitting lens configured to transmit light received from the second filter stack to the third filter stack. The second filter stack is oriented to reflect light received from the first filter stack onto the refractive beam splitting lens. The optical system is implemented in augmented reality devices, such as head mounted devices (HMDs), to combine images generated by the display with light received from external sources.
