New Military Goggles Combine Night Vision and Thermal Imaging
The United States Army wants to outfit its soldiers with the type of invisibility cloak that makes characters in the "Harry Potter" franchise disappear from sight.
Unfortunately, for the army, that's not possible, according to Martin Wegener, of the Karlsruhe Institute of Technology in Germany.
"Complete invisibility of macroscopic objects for all visible colors is fundamentally impossible," Martin told the New Scientist.
So the army will have to settle for “stealth fabrics.” It has requested all the companies manufacturing such materials to get in touch and is hoping to test the first prototypes within 18 months.
One option is "metamaterials," which are highly adaptive and uniquely structured at the microscopic level. First demonstrated in 2006, metamaterials can bend light around the wearer, essentially making them "invisible" from certain angles.
At worst, it is looking for something that can make soldiers "shadowless" in certain wavelengths – and is turning to lab-created materials for the solution.
