We have all been exposed to science fiction at some point. We have all seen or read the concept of holograms, whether it was the holodeck used in Star Trek or the holograms used to communicate in Star Wars. Now Japan has actually invented one you can touch and interact with. Researchers at Japan’s Digital Nature Group have used a new method to achieve this.
Famtosecond lasers were used to create the hologram. Earlier, they also used similar plasma lasers to show aerial 3-D plasma imagery. This time however, the researchers have come up with a hologram that can actually interact with people when you touch it.
In order to do this, the researchers have decreased the time of laser bursts to higher resolution famtoseconds. Lower resolution famtoseconds and nanoseconds were at first considered to create the holograms. The holograms are created from voxels, which are points of light that plasma releases when the air is ionized by a laser’s focus. A star, heart, and tiny fairy have been used to represent the holograms.
The researchers are saying the holograms can be used for aerial holographic purposes as of right now, but cannot be used to create a real holodeck just yet.
The team will display its incredible new technology to the public however in the Siggraph 2015 exhibition. With this new technology it is suspected though that the researchers could soon recreate 3-D interface technology as we know it. This kind of innovation is undoubtedly going to stick soon enough.
