You can find instructions for doing so on the Rochester University website, and a paper describing the research on arXiv. Metamaterials can be used to make objects appear invisible by bending light around those objects through refraction instead of away from those objects by reflection.

It will not be useable for espionage purposes any time soon, but Howell and Choi imagine a more beneficent purpose for their invention: allowing a surgeon to operate without their view being obstructed by their hands, for instance, or allowing truck drivers to see through blind spots.Īnd, because the setup is so simple, anyone can grab some lenses and give it a try. However, this problem can be solved with a more complex configuration. This invisibility has a range of around 15 degrees as you can see in the video below at around the two-minute mark when Choi places his hand in between the lenses, the dead centre of the field is not included. Metamaterials can be used to make objects appear invisible by bending light around those objects through refraction instead of away from those objects by. When you see things, light from the object you are viewing enters your eyes and interacts with the rods and cones in your eyes. Light Hammer - (A bit more difficult to master) First, the Bender must create a Light Spear, then bend the Light atop the spear, flattening and expanding it, giving it width, then solidifying the top, creating the mallet, then the Light Hammer is created. This bends the light so that an object in the ring-shaped cloaking field is not visible to a person peering through the array, with the grid background appearing perfectly normal. Light Spear - Bending the light off the ground through the hands and gently lifting them off the ground straight up, creating the weapon. The off-the-shelf lenses are placed at such a distance from each other so as to allow the light to act in specific ways: first focusing it down to a fine point through one lens, then again through the next this is then repeated. The Rochester Cloak array, showing how the lenses bend light. "This is the first device that we know of that can do three-dimensional, continuously multidirectional cloaking, which works for transmitting rays in the visible spectrum," Choi added.Īs well as at least partially solving the viewpoint problem, the Rochester cloak also leaves the background undisturbed, without any warping, as has appeared in other devices.

"There've been many high tech approaches to cloaking and the basic idea behind these is to take light and have it pass around something as if it isn't there, often using high-tech or exotic materials," said professor of physics at Rochester University John Howell, who developed the Rochester Cloak with graduate student Joseph Choi. Cloak's on you: Scientists create 'invisible' objectįor the first time, researchers have made a cloaking device that works multidirectionally in three dimensions - using no specialised equipment, but four standard lenses.
