Indian origin researcher develops fog clearing `nano-camera` to make driving safer

London: Indian origin researcher has developed a camera that can see through fog, thus helping vehicles navigate through tough weather on their own and making driving safer.

The camera, created by a team led by Ramesh Raskar of the Camera Culture group at MIT`s Media Lab, uses off-the-shelf LEDs that strobe at nanosecond periods, New Scientist reported. The 3D " nano-camera" relies on time-of-flight photography, which measures how fast a light signal is reflected back to a camera to determine the distance of an object. The 500 dollars camera distinguishes between direct and scattered or diffracted light, so it could be used in vehicle collision-avoidance technology or medical imaging.
