Lasers Used To Create Interactive Holograms

Japanese researchers have created a hologram you can touch.

Researchers’ team from University of Tsukuba’s Digital Nature Group used special types of lasers i.e. a femtosecond laser which transmits usually in spurts ranging from 30 to 270 femtoseconds, where 1 femtosecond is a quadrillionth of a second.

Holy shit thats quick.

The DNG team generated variant shapes up to the mark of 1 cm cube which had a resolution of 200,000 dots-per second when settled at the maximum limit. This all was done merely by combining a Galvano scanner, a mirror and a light modulator. This high a speed literally means that holograms are able to act and respond to smart touch.

Yes I can spin the cube.

The group of volunteers who tested the holograms made by the researchers claimed that the holograms feel somewhere in between that of a static shock and a sandpaper (a little bit sting-y I presume). They are primarily built by using Voxels, which are the small points of plasma lights made when the laser energy ionizes the surrounding air.

Well at least I won't burn my fingers.
