A team of researchers in Japan lead by Akira Asano of Burton Inc. have developed a 3D aerial display capable of projecting text and imagery in mid-air. The Aerial Burton works by firing a 1kHz infrared pulse directly into a 3D scanner which in turn focuses and reflects the laser to a specific point in the air. Molecules at the end of the laser then ionize, releasing energy in the form of photons.
