Abstract: An optical assembly is configured to receive visible scene light at a backside of the optical assembly and to direct the visible scene light on an optical path toward the eyeward side. The optical assembly also includes a dimming layer disposed on the optical path, where the dimming layer includes a photochromic material that is configured to darken in response to exposure to a range of light wavelengths. An activation layer, included in the optical assembly, is also disposed on the optical path and includes an in-field dimmer. The in-field dimmer is configured to selectively emit an activation light within the range of light wavelengths to activate a darkening of a region of the dimming layer to dim the visible scene light within the region.

Abstract: A configurable occluder/dimmer for a near-eye display includes an array of polarization rotators and a polarization-selective scatterer downstream of the array of polarization rotators. The array of rotators and the polarization-selective scatterer are disposed between a pair of polarizers. The polarization-selective scatterer only scatters light at one of two orthogonal polarizations, thereby enhancing the achieved extinction ratio of the configurable occluder/dimmer. The configurable occluder/dimmer may be used in the near-eye display to provide occlusion effects rendering added virtual objects opaque, and/or to equalize contrast of the generated virtual imagery across the field of view of the display.

Abstract: A near-eye display based on a polarization-selective diffusive combiner includes a polarizer for polarizing impinging ambient light to have a first polarization state, and a polarization-selective scatterer downstream of the polarizer, for passing through the ambient light having the first polarization state substantially without scattering, while scattering impinging display light having a second polarization state orthogonal to the first polarization state. The display light at the second polarization state may be provided by a projector, the polarization-selective scatterer playing the role of a projector screen. A polarization-selective ocular lens may be disposed downstream of the polarization-selective scatterer for viewing images generated by the projector while propagating through orthogonally polarized light from outside environment.

Abstract: An example device may include an electronic display configured to generate an augmented reality image element and an optical combiner configured to receive the augmented reality image element along with ambient light from outside the device. The optical combiner may be configured to provide an augmented reality image having the augmented reality image element located within a portion of an ambient image formed from the ambient light. The device may also include a dimmer element configured to selectively dim the portion of the ambient image in which the augmented reality image element is located.

Abstract: Motion contrast depth scanning is disclosed herein. A disclosed example apparatus includes an illumination source that is to provide at least one of spatial or temporal changes to light emitted from the illumination source to a scene. The example apparatus also includes a motion contrast sensor, where pixels of the motion contrast sensor are to detect changes corresponding to the scene, and where the motion contrast sensor is to report measurements when a pixel change exceeds a threshold. The example apparatus further includes a processor to determine at least one of a reflectance, a depth, or movement of the scene based on the reported measurements by the motion contrast sensor.
