Three-dimensional plasma holograms that can be touched - VIDEO PDF Print E-mail

Remember, how long have you really hit a hologram? We have become accustomed to this technology, the next step in its development must be something truly groundbreaking. And it seems that this breakthrough has already committed - we had three-dimensional plasma displays, which can be touched, and that, in turn, respond to touch.

Researchers from Digital Nature Group (DNG) from the University of TsUKuba, Japan, presented their innovative technology generate tangible images using lasers, mirrors, lenses and a special software package.

These tiny displays work because lasers can communicate gases constituting the air, enough energy to its electrons leave their orbit. This ionization process causes air to emit light, as it becomes a plasma. DNG command uses an incredibly short femtosecond laser pulses (femtosecond refers to the second the same way as one calorie refers to a megaton of TNT), to initiate a simultaneous excitation of 200.000 points airspace in three dimensions. These voxels ("three-dimensional pixels") are perceived by the eye and it is safe to touch.
However, safety of plasma is not the only innovation in this technology. Because this method uses lasers are so fast, the camera is located under the display, allows the system to respond to touch in real time.

The next step for DNG will increase the size of holograms and to seek opportunities to use other materials than air. This technology can be used to create displays of anything - from fluorescent plates to ordinary water. In the not too distant future this method may give us a transparent touch screens and interfaces that are able to really respond to touch.
