    Abstract: A multiview camera and multiview imaging system provide a plurality of different cropped images corresponding to a virtual screen located in a scene. The multiview camera includes a plurality of cameras configured to capture different images of a scene that have an overlapping portion in common. The multiview camera further includes an image processor configured to provide cropped images from the captured images according to a cropping window defined within the overlapping portion. The cropping window corresponds to a virtual screen located within the scene. An arrangement of the cameras corresponds to an arrangement of views of a multiview display configured to display the cropped images. The multiview imaging system further includes the multiview display.

    Abstract: A multiview backlight and a multiview display employ multibeam elements configured to provide a tilted plurality of light beams having different principal angular directions corresponding to different view directions of a plurality of views of the multiview display. Further, the tilted plurality of light beams has a tilt toward a center of a view zone of the multiview display to provide converging views. The multiview backlight includes a light guide and an array of the multibeam elements. The multiview display further includes multiview pixels that include view pixels to modulate the tilted plurality of light beams having the tilt and the different principal angular directions.

    Abstract: Unidirectional grating-based backlighting includes a light guide and a diffraction grating at a surface of the light guide. The light guide is to guide a light beam and the diffraction grating is configured to couple out a portion of the guided light beam using diffractive coupling and to direct the coupled-out portion away from the light guide surface as a primary light beam at a principal angular direction. The unidirectional grating-based backlighting further includes a reflective island in the light guide between the light guide surface and an opposite surface of the light guide to reflectively redirect a diffractively produced, secondary light beam out of the light guide in a direction of the primary light beam.

    Abstract: A polarization-mixing light guide includes a plate light guide and a polarization retarder within the plate light guide. The light guide is to guide a beam of light at a non-zero propagation angle. The light beam includes a first polarization component and a second polarization component. The polarization retarder is to redistribute the first and second polarization components of the guided light beam into predetermined combinations of the polarization components. The light guide is to preferentially scatter out a portion of the guided light beam having the first polarization component. A three-dimensional (3-D) electronic display includes an array of multibeam diffraction gratings at a surface of the plate light guide to preferentially couple out the first polarization component of the guided light beam as a plurality of light beams having different principal angular directions.
