Chinese spy camera

A powerful new laser camera developed in
China can track foreign military satellites--and
even read their serial numbers from over 100
km away.
Created by the Chinese Academy of Sciences
Aerospace Information Research Institute, the
system captured millimeter-level resolution
images during tests at Lake Qinghai, a
breakthrough that challenges the limits of long-
'ange surveillance, writes South China Morning
Post. The device uses a synthetic aperture lidar
system, combining a 103-watt laser with real-
time digital processing to achieve detail 100
times finer than conventional telescopes. It can
detect objects as small as 1.7 mm and measure
distances with an accuracy of 15.6 mm
