Femtosecond Lasers Create 3D Images in Mid Air Which You Can Touch
|A Fairy in Mid Air|
Femtosecond lasers are the latest cutting edge technology in ophthalmology and have led to the development of many new techniques and refinement of old techniques in refractive surgery.
Now scientists from the University of Tsukuba, Utsunomiya University, Nagoya Institute of Technology, and the University of Tokyo, have used femtosecond lasers to produce 3D images in mid air by ionization, which can be touched and interacted. The most important feature of the system is that power of laser is reduced to such an extent that it is not harmful to the skin. Plus interacting with the image generates small shockwaves under the skin, so one can have haptic feedback as well.
