Abstract: A display includes a source that establishes an exit pupil of far field content, a reconvergent sheet disposed along an optical axis to receive light of the far field content, the reconvergent sheet being configured to reconverge the far field content in position space, a reflective surface disposed along the optical axis for reflection of light of the position space back through the reconvergent sheet after reflection off of the reflective surface to re-form the exit pupil of the far field content, and a splitter disposed along the optical axis between the source and the reconvergent sheet and configured to redirect light exhibiting the re-formed exit pupil in a direction offset from the optical axis.

Abstract: The description relates to devices that emit light from a light source. One example device can include a reflector extending along an arc and oriented in light receiving relation relative to the light source. The reflector can have a cross-sectional reflector profile taken transverse to the arc that includes a first portion having a swept profile that transitions to a second portion having a reverse swept profile.

The image plane is disposed at an image conjugate distance from the second lens array assembly in accordance with the object conjugate distance.

Abstract: This document describes techniques and apparatuses for implementing a hybrid concentrator for a backlight. The backlight includes a light guide and multiple light sources positioned along an input end of the light guide. The backlight further includes multiple hybrid concentrators that each include a lens in a central region of the concentrator and one or more total-internal-reflection (TIR) zones. Each hybrid concentrator is positioned between a corresponding light source and the light guide, and is configured to concentrate light into the light guide. The light guide then projects the concentrated light to illuminate a modulating display panel to form images for viewing.

Abstract: Remote depth sensing techniques are described via relayed depth from diffusion. In one or more implementations, a remote depth sensing system is configured to sense depth as relayed from diffusion. The system includes an image capture system including an image sensor and an imaging lens configured to transmit light to the image sensor through an intermediate image plane that is disposed between the imaging lens and the image sensor, the intermediate plane having an optical diffuser disposed proximal thereto that is configured to diffuse the transmitted light. The system also includes a depth sensing module configured to receive one or more images from the image sensor and determine a distance to one or more objects in an object scene captured by the one or more images using a depth by diffusion technique that is based at least in part on an amount of blurring exhibited by respective said objects in the one or more images.
