Like a child concentrating sunlight with a magnifying glass, intense laser light can be “printed” into a tiny spot in the air. The system, has a possible value for advertisers, but could be used to send alerts and evacuation advisories during major natural disasters because they can be seen day and night and do not require screens.
The company that has developed this technology comes from Japan and is called Burton Inc. Here you see a projection that they are working on and hope to present in the near future. Instead of projecting three walking men, they’re also thinking on a version that projects the word ‘TSUNAMI’.
As for now, their light printers can only project 5 meters high, creating free-floating images like this.
As said, it works quite like how a child uses. magnifying glass. Light is focussed throuhpgh a lens towards. point in mid-air. This makes the molecules there emit white light that looks like a cross between a tiny explosion and a bright LED.
