Researchers from the University of Science and Technology of China have created a powerful laser device capable of reading text from nearly a mile away. They utilized a technique called intensity interferometry, originally developed for astronomy, to collect light intensity data from their eight infrared laser beams. This innovative system can detect letter shapes as small as three millimeters. The technique's ability to operate effectively despite atmospheric interference opens doors for practical applications, such as in surveillance or remote identification of objects, although ethical considerations will be crucial moving forward.
The team from the University of Science and Technology of China utilized eight infrared laser beams to accurately picture the text from an object 0.85 miles away.
By employing intensity interferometry, the researchers achieved remarkable sensitivity, revealing details as fine as individual letters, only three millimeters wide.
