British Ministry of Defence drew worldwide media attention in October 2007 when he announced that the successful tank invisible to the human eye. Although the British government is keeping information to himself, he issued the basic idea behind the technology.
The tank is covered in silicon, effectively turning the vehicle in a highly reflective film screen. Video cameras placed on the container in real-time images of the environment and projectors display images on the surface of the tank. For observers of secret trials conducted by the British Army in October 2007, the only thing visible was the images of the terrain projected onto the tank.
British plans for military tanks ready for battle by 2012, but this technique can be short-lived due to some shortcomings. Cameras or projectors can fail, and from different angles, the tank can be seen. This is somewhat cumbersome and difficult way to make an object invisible (HowStuffWorks discussed this technique in another article on invisibility cloaks). The use of cameras and projectors smoke and mirrors creates an optical illusion style, and a leading researcher in the British test was not fully satisfied with the technology.
“The next stage is to make the tank invisible without [cameras and projectors],” physicist Sir John Pendry says Daily Mail “, which is complex and complicated, but possible.”
In addition to Pendry universities around the world and the United States military, exploring the possibilities of actually making an object invisible using next generation technology to disguise that fact manipulate light. U.S. Defense Advanced Research Projects Agency (DARPA) – the Pentagon’s research wing has received the green light for funding of 15 million dollars over three years to investigate urban obfuscants. This project is an ambitious attempt to create a protective shield for use by soldiers in urban combat situations. Shield to be opened quickly in tight spaces and protect soldiers from enemy fire will be a great asset, but DARPA does not stop there. This shield will also be able to make the invisible soldier under him, and it would be healing, which means that if the bullet fails to get through the shield material can be repaired.
Chances are, DARPA will be successful in its goal – eventually. Physics are already in place to make possible, and when the technology to create the parts become available over the next decade, these devices leave to cover the field of science fiction and enter reality.
But how is this possible? How to manipulate light? Everything is based on some very small particles. Read the next page for metamaterials.
