Abstract: A holographic display device and a method for generating a hologram are disclosed. The holographic display device generating a hologram may include a storage unit and a control unit. Herein, the storage unit may store at least one look-up table each having a partial size of a full size of sub-holograms for reconfiguring object points, wherein the object points are included in a scene reconfigured of the generated hologram. And, the control unit may use at least one look-up table each having the partial size, so as to calculate hologram values of the sub-holograms for reconfiguring object points, wherein the object points are included in the scene, and then the control unit may generate the hologram by overlapping the hologram values of the sub-holograms.

Abstract: A scanning projector including a light source unit including a plurality of laser light sources; a mirror unit including a plurality of mirrors which transmit or reflect light beams output from the light source unit; a light synthesizer which synthesizes the light beams transmitted or reflected by the mirror unit; a Micro-Electro-Mechanical-System (MEMS) scanner which reflects incident light and performs scanning of the light in a horizontal direction and a vertical direction; and a light reflection unit which reflects light, having passed through the light synthesizer, to the MEMS scanner. Further, the light synthesizer includes a ½ wavelength plate converting a first polarization of the light beams transmitted or reflected by the mirror unit into a second polarization, and a Polarization Beam Splitter (PBS) surface synthesizing the light beams polarization-converted by the ½ wavelength plate into the second polarization with the light beams having the first polarization.
