An augmented reality display device configured to be disposed on a head of a user includes a display, a relay lens set, a beam splitting module, and a curved mirror. The display is configured to emit an image beam. The relay lens set is disposed on a path of the image beam. The beam splitting module is disposed on a path of the image beam from the relay lens set. The curved mirror is configured to reflect the image beam from the beam splitting module back to the beam splitting module. The image beam reflected by the curved mirror penetrates through the beam splitting module and is then transmitted to a pupil of the user. The beam splitting module includes a polarizer, a brightness enhancement film, and a phase retardation film stacked together in sequence from a side adjacent to the pupil to a side adjacent to the curved mirror.

Some embodiments of an apparatus may include: a tracking module configured to track viewer movement adjustments; and a light field image display structure configured to display a light field image using the viewer movement adjustments. Some embodiments of a method may include: projecting a beam spot on a viewer of a light field display; determining an estimated location of the beam spot reflected off the viewer; detecting an actual location of the beam spot reflected off the viewer; and determining image correction parameters based on a comparison of the estimated location and the actual location of the beam spot reflected off the viewer.

A three-dimensional viewing includes a pair of digital image sensors in communication with a pair of digital displays and controlled by a pair of processors to render three-dimensional images of samples on the displays.

A digital imaging system is provided with direct view of an object, having: an optical element configured to allow visible light to pass therethrough to a user's eye and to redirect light of non-visible wavelengths away from the user's eye; a display disposed between the user's eye and the object; a digital camera mounted outside a field of view of the user's eye and configured to obtaining imaging data from the light of non-visible wavelength; a redirection optic disposed so as to redirect the light of non-visible wavelength to the digital camera; and an image processor configured to process the imaging data from the digital camera and output the data to the display such that an image generated from the imaging data from the digital camera overlays an image produced by the impingement of visible light on the user's eye following the visible light's passing through the optical element.

An eyeglass of a 3D glasses, a fabrication method thereof and a 3D glasses are provided. The eyeglass of the 3D glasses comprises: a substrate (2), configured to have a 3D function; and a lens (1) having a converging or diverging function, laminated on the substrate. The eyeglass of the 3D glasses and the 3D glasses have a myopic or hyperopic function simultaneously.

Optical devices and cognitive prosthetics based on novel components for enhanced human vision, selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the parent patents are herein made both more useful in practical day-to-day use and are more widely applicable to improving the ability of a user to perceive visual stimuli.
