    Abstract: A beam deflector includes a first electrode layer including a plurality of line electrodes extending in a first direction and arranged parallel to each other in a second direction crossing the first direction; a second electrode layer separated from the first electrode layer by a predetermined distance to face the first electrode layer; and a deflection layer between the first electrode layer and the second electrode layer and having a plurality of optically anisotropic molecules controlled by an electric field formed between the first electrode layer and the second electrode layer. Each of the optically anisotropic molecules has an ellipse shape having a major axis and a minor axis, wherein the major axis is arranged to head for the first direction.

    Abstract: A display device including a meta surface is provided. The display device includes an image provider comprising a spatial light modulator configured to modulate light according to image information, wherein the image provider is configured to provide the light comprising the image information; an optical element configured to focus the light from the image provider; and a meta surface deflector positioned between the image provider and the optical element to deflect the light, and change a deflection direction of the light according to a polarization of the light so that a first position of the light of a first polarization focused by the optical element is different than a second position of the light of a second polarization orthogonal to the first polarization focused by the optical element.

    Abstract: Provided is a holographic display apparatus including: a spatial light modulator that modulates a wavefront of a reference beam to form a hologram image; an optical element arranged to change a position of a viewing window of the hologram image off-axis by a first angle; and an image processor that generates hologram data according to the position of the viewing window of the hologram image and a hologram image to be reproduced, and provides the hologram data to the spatial light modulator. The hologram image formed by the spatial light modulator is viewable from a side of the spatial light modulator.

    Abstract: An augmented reality (AR) device includes a light source; a light source-moving delta robot on which the light source is mounted, the light source-moving delta robot being configured to change a traveling path of light emitted from the light source by adjusting at least one of a position or a slope of the light source in a three-dimensional (3D) space based on a movement of the light source-moving delta robot; a display device configured to generate a first image by modulating the light emitted from the light source; and a combiner configured to combine the first image generated by the display device with a second image, which is different from the first image and is received from an external source, and output a combined image.
