  • Publication number: 20140085692
    Abstract: A hologram data processing method using a hologram fringe data format adaptive to a data encoding scheme includes configuring model data of a three-dimensional (3D) object corresponding to source data to be used for generating a hologram, computing hologram fringe data by applying a diffraction transform to a light wave transferred to a hologram plane based on the model data of the 3D object, setting, in the computed hologram fringe data, the hologram fringe data format adaptive to a data encoding scheme for reconstructing the hologram, reconstructing an optical hologram by applying the data encoding scheme to the hologram fringe data, and adjusting the optical hologram by comparing a reconstructed image of the optical hologram to a reconstructed image of a numerical hologram.
