BAE Systems has tested an ‘invisibility cloak,’ which can work over infra-red and other frequencies.Known as “Adaptiv,” the patented technology is based on sheets of hexagonal ‘pixels’ that can change temperature very rapidly. On-board cameras pick up the background scenery and display that infra-red image on the vehicle, allowing even a moving tank to match its surroundings. Alternatively, it can mimic another vehicle or display identification tags, reducing the risk of fratricide.BAE Systems engineers have combined the pixels with other technologies, which provide camouflage in other parts of the electromagnetic spectrum at the same time to provide all-round stealth, which will be developed further over the next few years.Learn more from BAE Systems.
