Device and method for printing dual holographic

Abstract

The present disclosure relates to a device for printing dual holographic, including a plurality of lasers that represents different wavelengths, a plurality of dichroic lenses and mirrors that combine beams output from the plurality of lasers into one beam and output the combined beam as a white beam, a plurality of beam splitters that separates the white beams output through the plurality of dichroic lenses and mirrors, transmit the separated white beams to a stereogram printing device, a wavefront printing device, and a reference beam, separates a beam heading to the reference beam, and transmits the separated beam to the stereogram printing device and the wavefront printing device, and a computer that controls the stereogram printing device and the wavefront printing device so that a hologram is printed with the beam transmitted through the beam splitters.
