Acoustically generated holograms
Literal (from Hack a Day:
I found this on [hackedgadgets] and checked out the paper describing the project. I’m not sure if it will generate any truly usable graphics any time soon, but the technology is pretty interesting. It combines six video channels and uses acoustic frequencies and tiny but simple looking transducers to vibrate the crystal that channels a laser to generate the hologram. (If I read that paper correctly) Surprisingly, a single nvidea chip generates all six channels for the system. Annoyingly, there’s a lack of info on MITs site, but there’s a nice group of images under the multimedia link of this article.
