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.
