A group of Japanese scientists have created touchable holograms, three dimensional virtual objects that can be manipulated by human hand. Using femtosecond laser technology the researchers developed ‘Fairy Lights, a system that can fire high frequency laser pulses that last one millionth of one billionth of a second. The pulses respond to human touch, so …
---This sounds rather interesting! This almost sounds like it could somehow eventually lead to the holodecks in the Star Trek the Next Generation TV series. I don’t personally see how such a thing could be truly possible, but it nevertheless sounds very interesting. Regular laser holograms by themselves are fascinating, and I wish that I could see a good, large, bright one in person. They’re easy to understand, but they aren’t easy to see, being that not too many people have powerful lasers. And for anyone who doesn’t know, a hologram is created by 2 laser beams hitting an object from different angles, with the results being recorded on film. Then when 2 lasers are later shot through the same film, the original object’s image is created due to its layout having been stored on the film, thus forming a hologram. So they are really very cool.
