Poster-Sized Holograms Printer

We have invented digital holographic printing with pulsed lasers in 1999. From then we are manufacturing printers capable to print digital master holograms in colour and motion. Those holograms, which we are calling i-Lumograms are viewable in any point source light and can be multiplied by the copying process invented by us in 2007 and realized in our Holograms Replicator.

Working principle: 

Information for digital 3D hologram is obtained from digital pictures pixels, so the hologram itself always has pixelated structure. Those holographic pixels are called holopixels (or hogels), currently the size of those is 0.8 x 0.8 mm or 1.6×1.6mm, each holopixel contains information from 600-1200 usual pixels with corresponding coordinates that are taken from different views of 3D scene imprinted. Depending on the printer’s model, each holopixel is exposed ether three times with red, green and blue laser radiation, or simultaneously with all three colours lasers.

Printer comprises of pulsed red, green and blue radiation laser and all necessary hardware and software to convert series of 600-1200 pictures of 3D scene into four-dimensional image (three spatial coordinates plus time) and imprint it onto photosensitive material.

Printer type: dual-mode pixel-matrix holographic printer capable of producing from digital data:

  • Reflection composite holograms and reflective composite HOE’s for direct viewing – H1 master;
  • Composite reflection holograms for transferring to H2 holographic displays.

Data acceptable for printing:

  • HoloCam movies
  • Any CAD program (Cinema 4D, 3D Studio Max, etc.)
  • Combination of the above

Holographic exposure speed:

  • Holograms in size from 13x18cm to 40x60cm – one square meter per 25 hours;
  • Holograms in size from 40x60cm to 100x150cm – one square meter per 6.5 hours.

Digital holographic printer –holographic image printing equipment hardware and software set. Performs dot-by-dot exposure of the special photofilm from the data obtained either from the HoloCam devices, or from CAD programs like Cinema 4D or 3D Studio Max. Maximum one print size – 1500 x 1000 mm, maximum printing speed – 1 square meter per 6.5 hours.
