An extended field of view (FOV) is provided by an exit pupil expander in a near-eye display system that uses a waveguide with multiple diffractive optical elements (DOEs) for in-coupling light, expanding the pupil in two directions, and out-coupling light to a system user's eye. Left and right in-coupling DOEs in-couple pupils respectively produced by a pair of imagers—one imager provides a left portion of the FOV and the other imager provides the right portion. The left portion and right portion of the FOV respectively propagate in a left and right intermediate DOEs which expand the pupil in a first direction and diffract light to an out-coupling DOE. The out-coupling DOE expands the pupil in a second direction, stitches the extended FOV together by combining the left and right portions of the FOV produced by the imagers, and out-couples the extended FOV to the user's eye.

An integrated binocular augmented reality smart glass, which comprises an integrated structure of glass temples, an imaging system, a nose pad, a battery module and a glass frame, and a circuit board processor module and a control system are integrated therein. The integrated binocular augmented reality smart glass has a small volume, a light weight and a strong mobile flexibility and is convenient in usage and interaction, and can be worn stably for a long time under various application scenarios without generating discomfort. The imaging system of the integrated binocular augmented reality smart glass is a multi-layer structure, and comprises filter glasses, display glasses and functional glasses, where the filter glasses and the functional glasses are respectively located at two sides of the display glasses and are mounted on the glass frame.

Monocular or binocular viewing systems worn on the head of a user are provided. Each monocular assembly comprises a display and an optical assembly including an optical relay and a partially transparent optical combiner taking the form of an inclined curved plate, each optical assembly arranged to form a second image at infinity from a first image displayed by a display. The optics are to be crossed such that, in the case of a binocular system, if one optical combiner is placed in front of the right eye of the user, the optical relay and the corresponding display are placed in a forehead-facing position above the left eye of the user and under the optical combiner located on the left-hand side. This arrangement is obtained by judiciously choosing the geometric parameters of the various optical elements, their curvatures and the form of their surfaces.

A mechanism is described for facilitating automatic view adjustment for computing devices based on interpupillary distance associated with users according to one embodiment. A method of embodiments, as described herein, includes facilitating sensors to detect a user within proximity of the apparatus such that eyes of the user face lenses of a computing device, and measuring a first distance between a first sensor and a second sensor of the sensors. The method further include measuring a second distance between a first pupil of a first eye of the eyes and a second pupil of a second eye of the eyes of the user, and adjusting a first lens or a second lens of the lenses to match the second distance with the first distance.

Aspects of the present disclosure relate to solid optical systems and methods for use in head-worn computing systems. An optical assembly may include multiple elements that are aligned relative to one another and then adhesively bonded together to preserve the alignment in an adhesively bonded optic, wherein the adhesively bonded optic includes at least one internal refractive surface and two or more internal reflective surfaces, and wherein the internal partially reflective surfaces comprise partially reflective surfaces that are protected by other elements in the adhesively bonded optic

A wearable image display device eliminates the need to adjust an image focus every time the device is used. The present invention includes a mounting module and a right image display module, and a left image display module. Each of the right image display module, the left image display module includes a reflective image modulation device, a lens, a light guide plate, and a plurality of half mirrors. The lens is disposed in a state eccentric to a predetermined value with respect to the reflective image modulation device. As a result, the present invention eliminates the need to adjust the image focus every time the device is used.

A lens assembly has two opposing surfaces, each surface introducing field curvature in a direction opposite of the field curvature introduced by the opposing surface, and thus the field curvatures introduced by the two surfaces at least partially cancel each other out, resulting in a net field curvature that provides for a substantially flat image plane or for an image plane with a specified curvature. The lens assembly may be implemented as a lens with two opposing Fresnel surfaces so that the field curvature in one direction introduced by one of the Fresnel surfaces is at least partially canceled out by the field curvature in the opposite direction as introduced by an opposing Fresnel surface. Alternatively, the lens assembly may be implemented as a lens with a positive continuous aspheric surface facing the user's eye and an opposing Fresnel surface facing the display panel.

An apparatus and a method are described herein related to the art of augmented reality type monitor virtualization. A monitor-virtualization system, such as a head-mountable device, an ophthalmic device or an intraocular implant, can render a virtual monitor in augmented reality. A liquid lens or an optical phased array can position the virtual monitor in space by optical means. A dimmable occlusion matrix can be additionally operated such as to make the image of the virtual monitor substantially opaque. A coordinator module can synchronize the activities of monitor positioning and occlusion masking. The virtual monitor can be anchored to real-world artifacts using bokode technology. Various dimming modes of the occlusion matrix reduce operator fatigue. The apparatus may operate in smart sunglass mode when the virtual monitor function is paused. The virtual monitor can be hidden or visualized differently when thresholds in terms of user geolocation or viewing angle are breached.
