Holograms aren’t new, but a desktop machine that spits them out could be available soon, presuming LitiHolo’s Kickstarter pans out. The machine will have a $1600 retail price and fits in a two-foot square. It can generate 4×5 inch holograms with 1mm hogels (the holo equivalent of a pixel).
The machine allows for 23 view zones per hogel and can create moving holograms with a few seconds of motion — like the famous kiss-blowing holograms.
Of course, you’ll also need a special self-developing film and a way to get 3D images into the printer such as software or a camera set up to do a 3D scan. In the 4×5 size, the film runs about $13 a plate which will create one hologram.
Since 5 inches is 127 mm the hogel resolution of the result is about 101×127, and the samples on the website and the video below certainly don’t look like they are in HD.
Will people pay $1600 for low-resolution holograms? More importantly, is there a market for grainy holograms that would let you earn back the investment? Maybe not, but that hasn’t stopped us from buying 3D printers and other workshop toys. Plus, if this catches on, what will be available in ten years time?
Of course, if you have the laser gear, you can already make your own holograms. You can even get kits that have most of what you need.
