Harry Potters Invisible Cloak a Reality…

                

Yes! It’s correct what you read just now, invisible cloak.  I am sure you all might have seen the Harry Potter series and the mystical, magical and wizardry world of Harry Potter. And of course how can you miss the Harry Potter’s Invisible cloak. As I saw Harry Potter's cloak I always envied him that even I could get that cloak. And again science has made it possible. An invisibility cloak is invented at Rochester university by professor John Howell.

             

The simplicity of this cloak is that it uses four standard lenses instead of High-tech specialized equipments as we may expect. It is first device that can do three-dimensional, continuously multi directional cloaking, which works for transmitting rays in visible spectrum.

       

The lenses are placed at such a distance from each other so as to allow the light to act in specific ways, first focussing it down to a fine point through one lens, then again through the next and is repeated such that the object in the ring shaped cloaking field is nit visible to a person peering through the lenses with background appearing normal. This invisibility has a range around 15 degrees.

            

It is imagined to be beneficial for allowing a surgeon to operate without their view being obstructed by their hands. It may help truck drivers to see through blind spots. It can be used in banks for safety purposes. It is also thought to be used for military applications and for security purposes.

           

One of the problem with this invisiblity cloak is that they work only if both the viewer and whatever is being cloaked remain still. This is practically not possible which has put forth a big challenge. And I hope this problem will be solved soon and Harry Potter's cloak wil be used for beneficial purposes soon. Enabling things from "fiction to reality"
