Invisibility Cloak, Technology | Canadian company has developed a real “invisibility cloak”

Harry Potter wore an invisibility cloak for the first time in the late 90s. Many might have dreamed of owning something similar, and now the cloak of invisibility was no longer just for wizards.

The Canadian company Hyperstealth, which designed the camouflage, has developed the Quantum Stealth – a kind of true invisibility cloak, which should be able to hide tanks and even entire military troops.

The material must be as thin as paper, write among other things Telegraph (for the customer), and consists of a lens that causes light to be bent around the object, thereby almost disappearing. Only the background appears. The material must also be able to bend ultraviolet and infrared rays.

A clip in the video made by the Canadian company shows a man walking behind a screen mounted in front of a wall. When he’s behind the scenes, we barely see anything moving, but instead we only see the wall in the background. Another clip shows a small saucer in front of what looks like a miniature lawn. As the camera moves across the plate, you will see three small cars standing in the yard.

It sounds pretty awesome, but it should still be relatively uncomplicated, and affordable too.

IFL Science explains that all materials have a refractive index, which says something about a material’s ability to conduct light. For example, you can put a spoon in a glass of water and see that the spoon looks bent when you look into the glass. In the same way, a swimming pool looks shallower than it actually is, because when light travels through two materials, its angle changes depending on the index of refraction. Knowledge of this in turn can allow you to create material that hides something very close or very far from it.

According to the website, it should work the same way when creating an image that looks like 3D when you view it from the right angle.

Thus, the material would not be able to provide a complete invisibility cloak. The object to be hidden will not appear, and the color will only be affected by the background, not by the object being hidden. However, the background will be distorted so you will see it something that.
