Abstract: A system to provide views of virtual content in an interactive space, e.g., an augmented reality environment, may comprise one or more of a light source, directional control device, variable power lens, beam steering device, optical element, and/or one or more physical processors. A light source may generate collimated light rays in accordance with virtual content to be perceived within a three-dimensional light field. A directional control device may controllable adjust direction of travel of collimated light rays toward a beam steering device. A variable power lens may be positioned to receive collimated light rays between a light source and a directional control device. A beam steering device may be configured to direct collimated light rays to locations on an optical element. An optical element may be configured to reflect collimated light rays in a focal plane of a perceived three-dimensional light field.

Abstract: Aspects of the disclosed apparatuses, methods and systems provide a wearable, augmented or virtual reality display system including two or more sets of backlight illumination arrangements. Each different set of backlight illumination is directed to a corresponding optical imaging system. The corresponding optical imaging system is designed to focus each set of illumination at a different distance. The selection of a particular optical focal distance is controlled by selecting the set of backlight illumination corresponding to the imaging system to provide the desired focal distance. As a result, selection of the backlight illumination determines at which distance an image is perceived by a user. When multiple backlight illumination sets are multiplexed with 2-D images, a single, 3-D image is perceived by the wearer of the display system.
