Hologram image normalization method for holographic printer

A holographic printing system comprising:

• a hologram generation system configured to generate a hologram for an n-th hogel constituting a hologram, to encode the generated hologram, and to normalize the encoded hologram, the n-th hogel being a hogel located at an n-th position among a plurality of hogels;
• and
• a holographic printer configured to load the normalized hologram on a spatial light modulator (SLM), to restore an original hologram from the hologram loaded on the SLM, to record the original hologram on a holographic material, to move a position of a stage where the holographic material is placed to a position on the holographic material where an (n+1)-th hogel is recorded, and to wait until the moved stage is stabilized,
• wherein generating, encoding, and normalizing for the (n+1)-th hogel by the hologram generation system are performed in parallel with loading and recording for the n-th hogel and moving and waiting for the (n+1)-th hogel by the holographic printer.

• encoding the generated hologram;
• and
• normalizing the encoded hologram,
• wherein the generating, the encoding, and the normalizing are performed in parallel with operations of:
• loading a normalized hologram for an (n−1)-th hogel on a spatial light modulator (SLM);
• restoring an original hologram from the hologram loaded on the SLM, and recording the original hologram on a holographic material;
• moving a position of a stage where the holographic material is placed to a position on the holographic material where an (n+1)-th hogel is recorded;
• and waiting until the moved stage is stabilized.
