Click photos at speed of light with this camera

An inexpensive multi-purpose 'nano-camera' that can operate at the speed of light has been developed by a team of MIT researchers, including Indian-origin scientists.

The $ 500 camera could be used in medical imaging and collision-avoidance detectors for cars, and to improve the accuracy of motion tracking and gesture-recognition devices used in interactive gaming.
The three-dimensional camera was developed by researchers in the Massachusetts Institute of Technology Media Lab.
The camera is based on "Time of Flight" technology in which the location of objects is calculated by how long it takes a light signal to reflect off a surface and return to the sensor.
However, unlike existing devices based on this technology, the new camera is not fooled by rain, fog, or even translucent objects, said co-author Achuta Kadambi.
