Screenless 3D Display
Japanese tech firm Aerial Burton has developed a portable 3D display that creates floating images in mid-air.
The projector uses a phenomenon called plasma emission to focus invisible infrared laser pulses at specific points in space, causing molecules at those points to release photons that are seen as bright flashes of light.
The result is a flashing display that is visible in all light conditions. The company initially plans to use the technology to create signage during emergencies, but it is also developing larger displays for advertising and entertainment.
"The biggest difference between our technology and other displays is that this is a screenless technology," director Akira Asano said in an interview with video news site DigInfo TV. "This is the only device that can show text and pictures in mid-air without using a screen."
