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.
