Japanese firm showcases ‘Bat-Signal’ of the future
A free-floating image created by firing lasers into thin air was unveiled in Japan yesterday, offering the possibility one day of projecting messages into a cloudless sky, as seen in the movie Batman.
Like the “Bat-Signal” that alerted the Caped Crusader to trouble brewing in Gotham City, its inventors hope that it might eventually be used to warn people of danger such as an approaching tsunami.
The company behind the technology, Burton Inc, showed off rotating spirals, fluttering butterflies and the outline of an apple hovering a few meters over a van loaded with the system.
Like a child concentrating sunlight with a magnifying glass, the device focuses intense laser light into a tiny spot in the air.
