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

Chinese scientists have engineered a laser-based imaging system capable of reading millimetre-sized text from 1.4 kilometres away, overcoming atmospheric distortion through active intensity interferometry. This breakthrough, achieving a 14-fold resolution improvement, could revolutionise archaeology, environmental monitoring, and infrastructure inspection. Researchers are now focused on enhancing usability and integrating AI for real-time image rendering.
