AUGMENTED REALITY DEVICE BASED ON A CURVED WAVEGUIDE, METHOD FOR OPERATION OF THE SAID DEVICE, AUGMENTED REALITY GLASSES BASED ON THE SAID DEVICE Russian patent published in 2022 - IPC G02B27/01 G02B5/18 G02B6/10 

FIELD: augmented reality.

SUBSTANCE: invention relates to augmented reality devices based on a curved waveguide. The augmented reality device contains a projection system for projecting an undistorted image; an introductory optical compensator located in the path of light rays emanating from the projection system; a curved waveguide containing an introductory diffraction optical element and an output diffraction optical element. The output diffraction optical element with a variable period of the diffraction grating performs the function of an output optical compensator that converts the radiation beams of a distorted image at the output of the waveguide into parallel radiation beams for the output of an undistorted image.

EFFECT: possibility of projecting a virtual image without aberrations, distortions and image doubling.
