Japanese scientist invents 'invisibility cloak'
A Japanese scientist has developed a coat which appears to make the wearer invisible. The illusion was part of a demonstration of optical camouflage technology at Tokyo University.It is the brainchild of Professor Susumu Tachi who is in the early stage of research he hopes will eventually make camouflaged objects virtually transparent.The photograph was taken through a viewfinder that uses a combination of moving images taken behind the wearer to give a transparent effect.

It's hoped the technology will be useful for surgeons frustrated their own hands and surgical tools can block their view of operations and pilots who wish cockpit floors were transparent for landings.Story filed: 14:15 Wednesday 5th February 2003 Are you interested in this type of story?If you're an Orange customer you can follow these subjects on your phone.

The idea of an "invisibility cloak" has made the leap from science fiction books to an international patent application. Ray Alden of North Carolina is attempting to patent a "three dimensional cloaking process and apparatus" for concealing objects and people (WO 02/067196).

The idea hinges on carefully mimicking background lighting conditions to help render an object invisible, similar to how a chameleon blends in with its surroundings. The rear and front surfaces of an object are covered with a material containing an array of photodetectors and light emitters respectively.

The photodetectors on the rear surface are used to record the intensity and color of a source of illumination behind the object. The light emitters on the front surface then generate light beams that exactly mimic the same measured intensity, color and trajectory. The result is that an observer looking at the front of the object appears to see straight through it.
 
If they get it right, the criminals are going to love this thing. "You didnt see me take nothing, I was invisible!" Or people selling rip off versions that dont work. You know, getting people caught who thought they were sneaking around invisible.
