It can't quite handle bare flesh, though: not reflective enough. A team of physicists from Heriot-Watt University in Edinburgh has developed laser technology that can 3-D image an object up to a kilometer away. The system can accurately (within a millimeter) image even "uncooperative" objects -- meaning those that don't easily reflect laser pulses, like fabric. Though at a kilometer away, it can probably capture an uncooperative human, too. The imaging technique is called "time-of-flight," or To...
