This shows 3-D images of a mannequin (top) and person (bottom) from 325 meters away. The left-hand panels show close-up photos of the targets taken with a standard camera. In the center are 3-D images of these targets taken by the scanner from 325 meters away. On the right is a color-coded map showing the number of photons that bounce off the targets and return to the detector, with black indicating a low number of photons. Notice that human skin does not show up well using the scanner: the mannequin's face includes depth information, but the person's face does not.
