    摘要： A beam deflection layer includes: a first selective polarization conversion-splitter that splits first color light in an incident light beam into 1A color light and 1B color light having different polarization directions from each other; a first beam deflector that deflects the 1A first first color light in the light beam from the 1A first selective polarization conversion-splitter, a first selective polarization converter that converts polarization directions of the 1A first first color light and the 1B second first color light in the light beam from the 1A first beam deflector, and a 1B second beam deflector configured to deflect the 1B second first color light in the light beam from the first selective polarization converter. The first color light, the 1A color light, and the 1B color light each have a first wavelength band.

    摘要： A holographic display apparatus includes: a light source configured to emit light; a spatial light modulator configured to sequentially generate hologram patterns for modulating the light and to sequentially reproduce frames of hologram images based on the hologram patterns; and a controller configured to provide hologram data signals to the spatial light modulator, the hologram data signals being used to sequentially generate the hologram patterns. The controller is configured to further provide, to the spatial light modulator, diffraction pattern data signals for forming periodic diffraction patterns for adjusting locations of the hologram images to be reproduced on a hologram image plane, the diffraction pattern data signals being configured to move the periodic diffraction patterns on the spatial light modulator along a predetermined direction for each of the frames.

    摘要： An apparatus and method for processing a holographic image are disclosed. The apparatus calculates a first calculation result with respect to an image for the left eye and a first calculation result with respect to an image for the right eye and stores the results at different memory addresses of a storage. Thereafter, the apparatus calculates values of a waveform of light to be modulated by a spatial light modulator by performing a second calculation that uses all of the first calculation results stored in the storage. An image window of the image for the left eye and an image window of the image for the right eye are spatially separated from each other by the apparatus in a viewing window of a hologram image reproduced via the spatial light modulator.

    摘要： A holographic display device includes a light source configured to emit light, the light including first light of a first wavelength, second light of a second wavelength, and third light of a third wavelength; a spatial light modulator configured to form a holographic pattern to modulate the light emitted from the light source and to produce a holographic image; and a focusing optical system configured to focus the holographic image. The focusing optical system includes a fixed-focus optical system having a fixed focal length, and a variable focus optical system having a focal length that is changed by electrical control. The fixed-focus optical system is configured to focus the first light of the first wavelength, the second light of the second wavelength, and the third light of the third wavelength on different positions, respectively, on an optical axis to cancel a chromatic aberration by the variable focus optical system.
