Laser Scans Objects in 3D from Half a Mile Away
April 10th, 2013Via: Engadget:
3D scanning at a range of 0.62 miles? It just became possible, thanks to a laser camera developed by physicists at Heriot Watt University in Edinburgh, UK. You can pretty much see how it works from the images above — laser beams are bounced off the target and the duration of their return journey is measured precisely enough to detect millimeter depth changes even at extreme distances.
