New technology developed by a team of scientists from the Australian National University (ANU) allows you to “make the invisible visible”, to provide people with the opportunity see in the dark, revolutionizing night vision technology.
The invention of Australian scientists will make it possible to transform glasses or a car windshield into a kind of night vision device, simply by gluing a nanofilm made of a special material onto their surface. As a result, users of the updated devices will be able to distinguish various objects in the dark, including people and animals.
The created technology prototype based on nanometer-sized crystals can be used for protection, as well as for the safety of driving at night and walking in complete darkness.
A thin film made from nanometer-sized crystals hundreds of times thinner than a human hair is applied directly to glasses and acts as a filter to allow you to see in the dark. The technology is capable of converting infrared light, usually invisible to the human eye, and converting it into an image of the visible spectrum. It is noteworthy that the new technology works at room temperature and is based on the transmission of light photons through a nanofilm illuminated by a low-power laser.
The first developments related to the technology of obtaining nano-crystals for films were carried out back in 2016. After that, scientists worked to scale up the technology and make it easier to use in everyday life. To date, the first prototypes have been obtained, allowing you to create a film that, when glued to glasses or the windshield of a car, turns them into a kind of night vision devices.
The energy consumption of a low-power laser is much lower than what is needed, for example, for a laser pointer. Scientists are currently working on a commercial version of the nanofilm.
