    Abstract: Provided is an optically addressable spatial light modulator (OASLM)-based holographic display and a method of operating the same. The display includes an addressing unit including a light source unit emitting a plurality of recording beams, a driving mirror array including driving mirrors that each reflect a recording beam incident thereon, and a mirror member array including mirror members that each obliquely reflect a recording beam incident thereon, in which each of the driving mirrors corresponds to one of the mirror members. The recording beams, which are transmitted by the addressing unit, are focused onto the OASLM by micro lenses of a lenslet array.

  • Patent number: 9658378
    Abstract: An illumination unit is provided including a coherent light source; a projection optical element which focuses a light beam emitted from the coherent light source onto a focal plane; and a holographic optical element interposed between the coherent light source and the projection optical element, and having an interference pattern formed thereon. The holographic optical element diffracts the light beam emitted from the coherent light source and emits the diffracted light to the projection optical element. Here, the interference pattern on the holographic optical element may have information that diffracts the light beam and thereby cancels a diffraction of the light beam due to an aberration of the projection optical element.
