Abstract: The disclosure relates to augmented reality devices based on a curved waveguide. An augmented reality device is provided. The augmented reality device includes a projection system to project an undistorted image, an input optical compensator located on the path of light rays out-coupled from the projection system, a curved waveguide comprising an input diffractive optical element and an output diffractive optical element. The output diffractive optical element performs the function of an output optical compensator that converts the light beams of a distorted image at the output of the waveguide into parallel light beams to output an undistorted image. Augmented reality glasses comprising an augmented reality device are also proposed. There is provided the ability to project a virtual image without aberrations, distortions and doubling of the image.

Abstract: The disclosure relates to augmented reality devices, and more particularly, to augmented reality glasses and methods for operating the same. An augmented reality display device is provided. The augmented reality display device includes a projection system, an optical compensator positioned after the projection system, and a flexible waveguide. The flexible waveguide can change its curvature and comprises an input diffraction grating and an output diffraction grating. The optical compensator is configured to introduce pre-distortion to the image and optically zoom the image received from the projection system, the pre-distortion in the image and optical zoom of the image being opposite to those introduced by the flexible waveguide to the undistorted image in accordance with chosen radius of the flexible waveguide. Flexible diffraction grating distorts the pre-distorted image. The output diffraction grating outputs undistorted image to a user's eyes.
