Holographic printers - Geola - lasers and holography experts

Digital holographic printers Digital holographic printing with pulsed laser was invented by Geola in 1999. From then Geola is 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 used for copying.

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, currently the size of those holopixels is not less than 0.8 x 0.8 mm, each holopixel contains information from 600-1200 usual pixels with corresponding coordinates that are taken from different views of imprinted scene. Each holopixel is exposed three times witch red, green and blue laser radiation.

First digital holographic printer manufactured by Geola in 2001

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