3D Projection (without a screen)

A team of researchers in Japan lead by Akira Asanohave developed the technology they call ‘The Aerial Burton.’ The device works by firing a 1kHz infrared pulse directly into a 3D scanner, which focuses and reflects the laser to a specific point in the air. When the molecules reach the specified point at the end of the laser they ionize, releasing energy in the form of photons.
