Physicists at Scotland’s Heriot-Watt University have created a 3D imaging camera system capable of resolving depth on a millimeter scale at distances of up to one kilometer. Working much like a laser version of radar, the “Time-of-Flight” (ToF) measurement system “pings” a low-powered infrared laser beam off distant objects and records a pixel-by-pixel map using a detector that counts and positions individual photons as they arrive back at the source.
