China builds 'spy' laser that can read text smaller than a grain of rice from a mile away

Chinese scientists have developed a laser-based imaging system capable of reading text as small as one millimetre from 1.4 kilometers away. This technology, using active intensity interferometry, overcomes challenges like atmospheric distortion and poor resolution over long distances. It could revolutionize fields like archaeology, wildlife monitoring, and security, but raises privacy, surveillance, and ethical concerns.
