The Optical Society’s research group has created a new 3D laser printer that “produces digital 3D holograms with unprecedented levels of detail and realistic colors,” which offers a wider field of view, higher resolution and better color rendering than previous systems, according to a press release that presents a study that also appeared in Applied Optics.
This new “printer” can create holograms with a very wide field of view and full parallax, using specific photographic material developed by the same researchers as in this study. Thanks to holograms with full parallaxes, it is possible to reconstruct an object that can be seen from the side of the field of view up to 120°. The same models can be first generated on a computer, including scanners obtained with the help of special scanners.
According to researchers, this new printer, called CHIMERA, can be useful for creating copies of objects in color and high resolution, of course in 3D, for exposure, for example, in muzzles or art galleries, so you can look at the same object in detail, even if it is not in place. And all this without the need for special devices or equipment, such as glasses.
“Our 15-year research project aims to create a holographic printer with all the advantages of previous technologies by eliminating the known drawbacks of expensive lasers, low printing speed, limited field of view and unsaturated colors,” says Yves Ghent, one of the leaders of the research group. “We did this by creating the CHIMERA printer, which uses inexpensive commercial lasers and high-speed printing to produce holograms with high-quality colors covering a wide dynamic range.”
This printer is now used by researchers to create holograms up to 60 by 80 cm in size.
