Seeing around corners may not be possible for the human eye, but for this camera it’s a breeze. Researchers have developed a camera system that, within three seconds, can locate an object, hidden behind a wall, and track its movement. The system fires a stream of short pulses of light onto the floor just in front of the corner, and reads the light pulses reflected back from the object. Next the researchers hope to attempt a 3D reconstruction of the object.
