Japanese scientists developed the first hologram with stable colours

It is a bit distressing to see how holographic technology is still resolving such basic problems that we fear that it will take many, many years before we see holographic applications for the domestic market.

The last great small border have broken the Japanese scientists to gain the first hologram with stable colours. The traditional 1900–1971 are unable to maintain a uniform color. In other words, their colors change depending on the angle of view. The team of Professor satoshi kawata, the Department of applied physics of the University of Osaka, has managed to stabilize the color using the so-called 'surface Plasmon'.

The surface Plasmon are free electrons (not associated with any atom) which move in the tiny space of a few nanometers on surfaces such as metal. Each of these particles emitted at a frequency that determines its color.

Kawata team has scanned by laser image (an Apple) and it has overlapped several photosensitive layers that, by means of a halogen light, are able to excite electrons in an independent way to project the scanned image.

The result is a small little Apple floating on the metal plate. Interestingly, Kawata has not developed this technology thinking in commercial applications, but simply to demonstrate that it was possible. That Yes, when have they been discussed has not disgusted the possibility of further developed the idea to see what happens.

Before the us to jump at the prospect of asking with a phone as used by Palpatine, has to be said that the technology of surface Plasmon produces very small and static images, that Yes, in full color. This does not mean that more than one would give a heart if Apple will release an iPhone which the everlasting Apple logo is projected floating two inches from your phone. Again, the holography resolves a small problem. Let us hope that, even small cup to Cup, we can lead the surprise in a few years.
