Ground-breaking night-vision film can be applied to regular glasses
Scientists at the Australian National University (ANU) have developed a new type of night-vision technology that is the first of its kind. Taking the form of an ultra-thin film, it can be applied directly to glasses to act as a filter, needing only a simple laser to convert infrared light into images the wearer can see.
The researchers' groundbreaking film is based on nanocrystal technology that they've been working on for a number of years. These tiny particles are hundreds of times thinner than a human hair, and work by converting incoming photons from infrared light into higher-energy photons on the visible spectrum.
