The disclosure relates to augmented reality devices, namely to near-field displays, to planar waveguides with diffractive optical elements and displays based on such planar waveguides. The architecture of diffractive optical elements, performed in a waveguide and a method for operating the architecture of diffractive optical elements, eliminating image dispersion and expanding the horizontal field of view are provided. The method for operating the architecture of diffractive optical elements, expanding the vertical field of view and a device for displaying an augmented reality containing the proposed architecture of diffractive optical elements are provided. The augmented reality glasses includes the proposed augmented reality display device.

Waveguide architecture based on diffractive optical elements for augmented reality displays with a wide field of view

Provided is a waveguide guiding light to a target area, the waveguide including an input-coupling diffractive optical element (DOE) inputting the light into the waveguide, an expanding DOE expanding the light input into the waveguide through the input-coupling DOE, an output-coupling DOE outputting the light expanded in the waveguide by the expanding DOE to an outside of the waveguide, wherein the expanding DOE includes a plurality of expanding segments, and the output-coupling DOE includes a plurality of output-coupling segments.

Waveguide structure with segmented diffractive optical elements and near-eye display apparatus employing the same

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.

Eye position tracking sensor and method

Provided is a holographic waveguide including a waveguide element configured to guide light, and a diffractive optical element including an aberration correction hologram pattern, the diffractive optical element being provided adjacent to the waveguide element and configured to correct aberrations generated in the light traveling along the waveguide element by the waveguide element.
