Abstract: A curved waveguide-based augmented reality device is provided. The device includes a projector, and a curved waveguide. The waveguide has a shape of a concentric cylindrical meniscus and includes an in-coupling diffractive optical element and an out-coupling diffractive optical element, a grating period of a diffraction grating of the in-coupling diffractive optical element at each point of the in-coupling diffractive optical element is such that rays from one point of an initial image are input into the curved waveguide in each point of the in-coupling diffractive optical element at the same angle relative to a normal to a surface of the curved waveguide at a point of ray incidence, and at least at one point on each of the diffractive optical elements a diffraction grating period of the in-coupling diffractive optical element is equal to a diffraction grating period of the out-coupling diffractive optical element.

Abstract: The disclosure relates to augmented reality devices. An optical combiner configured to display augmented reality with user's vision correction is provided. The optical combiner includes a compensator, a waveguide having an in-coupling diffractive optical elements (DOE) and an out-coupling DOE, and a virtual image projector. The waveguide has a thickness gradient along the first and second side of the waveguide such that with propagation of virtual image-forming rays inside the waveguide from the in-coupling DOE to the out-coupling DOE, the incidence angle of the rays on walls inside the waveguide increases. The out-coupling DOE is placed opposite a user's eye, and is configured to output virtual image-forming rays, incident on the out-coupling DOE at an angle equal to or greater than the smallest angle of predetermined angular selectivity range of the out-coupling DOE, from the waveguide into the user's eye.

Abstract: A method of eye tracking includes: irradiating a light pattern, output from at least one collimated light source, to a cornea surface; detecting at least a part of the light pattern reflected from the cornea surface, the at least the part of the light pattern being guided by a sensor waveguide; obtaining a mapping image corresponding to the at least the part of the light pattern; and determining a direction of a gaze based on the obtained mapping image. The sensor waveguide used to determine the direction of the gaze is different from a waveguide for displaying output information.
