Abstract: Provided are an apparatus for displaying a holographic image and a method of controlling the apparatus. The apparatus for displaying the holographic image includes a controller, a light source, an optical system, a spatial light modulator, a filter, an electric optical scanner, a multi-channel projection optics, and a screen. The spatial light modulator modulates a light beam passing through the optical system according to a predetermined subframe sequence of holographic image frames, the filter performs spatial-angular filtering of the modulated light beam to exclude parasitic diffraction order components from the modulated light beam, and the electric optical scanner directs the modulated and filtered light beam towards a corresponding channel of the multi-channel projection optics and forms a plurality of viewing zones on a focal plane of a field lens provided in the screen.

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.
