Title:
CONTINUOUS HOLOGRAM RECORDING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/106431
Kind Code:
A1
Abstract:
A continuous hologram recording method is provided. A holographic printer according to an embodiment of the present invention comprises: a light source that emits light; a modulator that modulates the light emitted from the light source, to generate a holographic fringe pattern in units of hogels; a stage having placed thereon a hologram recording medium on which a holographic fringe pattern generated by the modulator is to be recorded in units of hogels; a first driving unit that moves the position of the stage in a first axial direction by using a first-type motor; and a second driving unit that moves the position of the stage in a second axial direction by using a second-type motor different from the first type. Accordingly, continuous hologram recording is enabled by appropriately implementing a motor that moves the stage on which the hologram recording medium is placed, according to vibration characteristics, thereby remarkably reducing the printing time for large holograms, which used to take several days to tens of days, and thus accelerating the commercialization of hologram printing.
