The MIT video camera capable of shooting with a shutter speed of 1 trillionth of a second. Recently, scientists have developed a way to shoot around the corner with this camera and laser.
The laser emits pulses of light lasting a few femtoseconds. These pulses are reflected and scattered photons and a part falls into thecamera lens. Due to the fact that the camera has a time resolution of 2 picoseconds (during which time a photon flies about 0.6millimeter), you can determine how far to overcome the reflectedphotons. Slightly changing the direction of the laser beam, you can collect enough data to reconstruct three-dimensional picture of the object, hidden around the corner. Details - on video:
