Chinese scientists have achieved millimeter-level high-resolution imaging technology at a distance of 1.36 kilometers.

Journalists learned on the 12th from the University of Science and Technology of China that Pan Jianwei, Zhang Qiang, Xu Feihu, and others, together with research institutions such as the Xi'an Institute of Optics and Precision Mechanics of the Chinese Academy of Sciences, have proposed and experimentally verified for the first time the technology of active optical intensity interferometry synthetic aperture technology, achieving high-resolution imaging of millimeter-level targets 1.36 kilometers away. The imaging resolution of the experimental system is about 14 times higher than that of a single telescope in an interferometer. The relevant results were recently published in the international authoritative academic journal "Physical Review Letters".
