The advancement in science is making what we may have thought of as impossible, probable. Humans may become invisible as the extra terrestrials which are considered to be probably invisible. A new technology provides a way to this. In this paper a scientific technology that is used to implement this idea is presented. The optical camouflage technology is one of the famous scientific technologies which helps in the invention of a new type of cloak called the invisible cloak. This is one of the big revolutions created in the area of virtual reality. It is just a concept of reflection of light by the cloak. The person who wears this cloak will feel as just what he feels with the ordinary cloaks but the person will be invisible to the outside environment. This is the main advantage of this cloak. There are many other interesting features present in this paper about this cloak.

Although optical is a term that technically refers to all forms of light, most proposed forms of optical camouflage would only provide invisibility in the visible portion of the spectrum. The research on the concept of invisibility was started in 1977 and was very successfully accomplished in 2003. Initially Professor Tachi from the University of Tokyo said that he had first had the idea of developing something to make objects invisible in 1977. But the imag e was flat and unrealistic. He came up with retro-reflective material which causes the coat to act as a screen and gives a transparent - or invisible - effect. Similarly, Duke University is using microwave beam deflection, making it appear almost as if nothing were there at all. . If you’ve seen the movie “Harry Potter” then you may recognize the idea of an invisibility cloak.
