<p>The present invention relates to a holographic display device, and the holographic display device may include: an input optical unit (input optical unit) capable of irradiating a coherent parallel light (coherent plane wave); a spatial light modulator capable of irradiating the coherent plane light in a plurality of directions so as to generate a plurality of diffraction beam (diffraction beam), or capable of irradiating in a single direction so as to generate a hologram-modulated high-order diffraction beam; and an imaging optical unit using at least one diffraction beam so as to play at least one hologram stereoscopic image to a reproducing area (imaging area).</p> |
