Japanese scientists created the first holograms to be touch-manipulated using an exciting technology based on femtosecond laser.
The incredible creation renders three dimensional holograms that can be touch-manipulated and safe to touch. The science fiction of old is becoming our modern world’s reality. The three dimensional holograms are not only safe to touch, but they are highly interactive and can be easily manipulated with just the touch of a fingertip.
The three dimensional holograms projected with the femtosecond laser technology are created at incredible speeds: one millionth of one billionth of a second. The Japanese scientists behind this innovative idea are fully engaged with their work at the Utsunomiya University Center for Optical Research and Education.
The lead scientist is Doctor Yoichi Ochiai, working with the Tsukuba University. A media artists as well who recalls enjoying Microsoft 3D Moviemaker and creating music in a one-man-show fashion, Doctor Ochiai also won the title “Digital-Age Alchemist”.
Using femtosecond laser technology or Fairy Lights as the technology is popularly known, Japanese scientists created the first holograms to be touch-manipulated. The research paper describing the exciting new innovation states that the applications of the three dimensional holograms could range from architecture to medicine to entertainment.
Doctor Ochiai declared during an interview:
“People’s daily lives would change if we use a bigger laser in a bigger space where people can interact with it, and to see how it can be used in situations where three-dimensional communication is necessary such as a construction site or in the medical field”.
Before the presentation of the three dimensional holograms for the public, the Digital Age Alchemist presented a paper explaining the concept in August. The paper, titled “Fairy Lights in Femtoseconds: Aerial and Volumetric Graphics Rendered by Focused Femtosecond Laser Combined with Computational Holographic Fields” was first presented before the audience present at the Siggraph 2015 conference, taking place in Los Angeles.
A demonstration then followed, with the Japanese scientists preparing a system with several high-intensity and rapid-speed lasers. Completed by mirrors and cameras, the complex system directed the voxels into creating a hologram at a 200,000 dots/sec resolution.
The three dimensional holograms created with the femtosecond laser technology are safe to our skin. If slower speeds were involved, then the heat would burn our skin. However, the holograms are meant to be touch-manipulated from one meter away to as close as the scientists wish.
Any object under the width of 8 mm can float as a three dimensional hologram.
