Researchers at the Australian National University (ANU) have developed a special film that is expected to be used to easily manufacture night-vision glasses. The technology uses nanoscale crystals to make infrared rays visible to the human eye. The thin film, described in an article in the journal “Advanced Photonics”, is the first of its kind and could one day be applied to standard glasses. The researchers say that it could make driving at night or walking home in the dark safer. It could also support police officers and security guards in their work, reducing the chronic neck injuries caused by the night-vision devices that are commonly used today. “We have made the invisible visible,” said lead scientist Dr Rocio Camacho Morales. Director of the ARC Centre for Excellence in Transformative Meta-Optical Systems (TMOS) and ANU professor of physics Dragomir Neshev said it was the first time that infrared light had been successfully turned into visible images on an ultra-thin screen anywhere in the world.
