Abstract: The present invention relates to augmented reality, and in particular, relates to an augmented reality display device. The display device includes: a device body, configured for a user to wear the display device; a transparent lens portion, configured for the user to see a real environment picture when wearing, at least a portion of a region of the transparent lens portion being a display region; a wireless transmission module, configured to receive virtual image information from the smart mobile terminal; and a processor, configured to process the virtual image information and display a corresponding virtual image picture, such that the virtual image picture is superimposed on a real environment picture.

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.

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: A system configured for providing views of virtual content in an augmented reality environment may comprise one or more of a first display, a second display, an optical element, one or more processors, and/or other components. The first display and second display may be separated by a separation distance. The first display and second display may be arranged such that rays of light emitted from pixels of the first display may travel through the second display, then reflect off the optical element and into a user's eyes. A three-dimensional light field perceived with a user's field-of-view may be generated. Distances of the first display and/or second display to the optical element may impact a perceived range of the three-dimensional light field. The separation distance may impact a perceived depth of the three-dimensional light field and/or a resolution of virtual content perceived with the three-dimensional light field.

Abstract: A lens system includes a tube lens and a lens assembly, with the tube lens disposed between an optical sensor and the lens assembly. The lens assembly is disposed between the tube lens and an imaged object. In order to solve the problem of some lens systems having focal lengths that are shorter than the working distances of the lens systems, one aspect of the inventive subject matter described herein provides the lens assembly with a negative lens and plural positive lenses. A first positive lens is located between a second positive lens and an imaging plane, the second positive lens is located between the first positive lens and the negative lens, and the negative lens is located between the second positive lens and the tube lens.

Abstract: Methods, systems, components, and techniques provide a retinal light scanning engine to write light corresponding to an image on the retina of a viewer. As described herein, a light source of the retinal light scanning engine forms a single point of light on the retina at any single, discrete moment in time. In one example, to form a complete image, the retinal light scanning engine uses a pattern to scan or write on the retina to provide light to millions of such points over one time segment corresponding to the image. The retinal light scanning engine changes the intensity and color of the points drawn by the pattern by simultaneously controlling the power of different light sources and movement of an optical scanner to display the desired content on the retina according to the pattern. In addition, the pattern may be optimized for writing an image on the retina. Moreover, multiple patterns may be used to additional increase or improve the field-of-view of the display.

Abstract: Methods and systems for autofocusing of an imaging system are presented. Provided is an imaging system and an optical interferometry system for generating one or more images corresponding to a target region in a subject. The method provides calibration information that identifies a focal position of the optical interferometry system corresponding to a determined focal position of the imaging system. A subsequent focal position of the imaging system is determined for generating a desired image corresponding to at least one of another target region in the subject and another position of the target region relative to the imaging system based on the calibration information.
