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.
