Chinese scientists have built a surveillance camera with unprecedented resolving capabilities. The powerful laser-based delivered millimeter-level resolution from 100 kilometers (62 miles) away, an achievement previously thought impossible. The scientists from the Chinese Academy of Sciences’ Aerospace Information Research Institute tested the new camera system at Qinghai Lake in remote northwest China, South China Morning Post reports. During the test, the synthetic aperture LIDAR (SAL) system looked at a target 101.8 kilometers away across the large lake and could decipher details just 1.7 millimeters across (1/16 inch). The SAL measured the distance to the objects within a margin of 15.6...
