Japanese scientists unveil floating 3D projection

The 'bat signal' of the future: Free-floating laser images could be fired into the sky to alert people to disasters

The bat signal that alerted the caped crusader to trouble brewing in Gotham City could soon become a reality.
A free-floating image created by firing lasers into thin air was today unveiled in Japan, offering the possibility if one day of projecting messages into a cloudless sky.
Like the bat signal, its inventors hope that it might someday be used to warn people of danger, such as an approaching tsunami.

The company behind the technology, Burton, showed off rotating spirals, fluttering butterflies and the outline of an apple hovering a few metres over a van.

'The biggest feature of our technology is that we can concentrate light on one spot and make it emit light wherever we like,' said Akira Asano, researcher and director of Burton.
The bursts of light come hundreds of times a second, and as the beam moves, are able to form what appear to the naked eye as rudimentary three-dimensional images.
Researchers said the system, as well as having possible value for advertisers, 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

CATHEDRAL USES SMARTPHONE WINDOWS TO CREATE A LASER SHOW

Dappled colourful sunlight filtering though stained glass windows and flickering candlelight may spring to mind when thinking of churches.
But one cathedral in France has got a more hi-tech solution to creating an inspiring space.

The lighting changes in response to text messages sent from people’s smartphones, to a number used by the cathedral.
Artist Filipe Vilas-Boas created the installation, Shooting Thoughts, in the cathedral, where the laser beams create what looks like a constellation of stars as well as a large cross.
The artist says that the ‘lines’ and ‘spots’ of light resemble caught spirits being called to heaven.
He thinks that by looking up, worshippers are encouraged to think and to ‘communicate with heaven’.
The beams use the cathedral’s Gothic architecture as pathways before reaching the centre of the vaulted ceiling to form a cross.

'We could go by car anytime 24 hours a day into a disaster zone and help send information and warnings,' said Burton chief executive Hideki Kimura, adding the images could offer alerts to people who could not hear conventional radio.
The technology, which was unveiled at a science museum in Tokyo, can currently display images five metres above the device.
But the company is aiming to double that height, he said.
The company, based in Kawasaki City southwest of Tokyo, hopes to start negotiations next year with businesses and municipal bodies on putting the system to eventual practical use.
