Infrared holography lets firefighters see through fire and smoke
As reported on The Verge. By Jeff Blagdon It isn’t easy to see through the smoke and flames in a burning building, but it’s crucial for emergency responders like firefighters, who need to be able to tell if people are trapped inside. To solve the problem, researchers at Italy’s National Institute of Optics have come up with a technique that one-ups conventional infrared camera technology by ditching an optical lens in favor of a laser, using…
