Is 3D technology the next big wave in video? Or should we skip right ahead to holography? New research is developing ways to stream almost-live video to holographic display, providing a three-dimensional, realistic image without the need for those dorky plastic 3D glasses. And before you ask–yes, this does bring us one step closer to living in a Star Wars world, where holographic princesses deliver desperate pleas for help.
This is the first time researchers [have demonstrated] an optical material that can display “holographic video,” as oppose to static holograms found in credit cards and product packages. The prototype looks like a chunk of acrylic, but it’s actually an exotic material, called a photorefractive polymer, with remarkable holographic properties. [IEEE Spectrum]
The prototype, produced by Nasser Peyghambarian and colleagues at the University of Arizona and Nitto Denko Technical Corporation, displays a holographic image that can be updated every two seconds. This is much better than the four minutes between updates seen in the team’s last prototype, and it gives the audience an almost-real-time representation of what’s happening on the other end of the communication (be it in the other room or across the country). The team expects to continue improving their technology, enabling larger pictures and shorter refresh times.
