8:41 AMThe laser projector that creates real 3D shapes in the air!
Japanese National Institute of Advanced Industrial Science and Technology (AIST) has developed a device that uses lasers to create a real three-dimensional image, like shapes in the open air. The Institute has demonstrated the development to February 7, showing at the same time the possibility of creating 3D shapes using white lasers
The projector is designed in collaboration with Keio University and Burton Inc. (Kawasaki).
To create a "real" three-dimensional image, it uses laser light, that focused by lenses in points to space above the projector and creating at these points the process of plasma emission of nitrogen and oxygen.
The laser operates in the invisible to the human eye range of light, but the emission cause the glow. Thanks to the fact that the glow continued for a limited time, device is capable to reproducing three-dimensional shapes and moving the focus point.
During the demonstration, the laser was operated at a frequency of 100 flashes per second, creating shapes in the air at a height of 50 cm from the projector. Air heating with a laser cause expansion of the air, so the process is accompanied by a characteristic "crackling". At present, the distance over which the device can project an image is limited to 2-3 meters. Further work on the laser will significantly increase this parameter and use more colors.
Perhaps in the near future we will see floating in the air 3D advertising. Or even be able to use it in games.
And maybe it will be used in work with computers or other devices. This is impressive!
If we will live - we'll see it! :)
