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.
