Invisible Raindrops

Rain — the scourge of the night driver! Too many times have distracting droplets proved an annoyance for those traveling roads after dark. New technology co-developed by Intel and Carnegie Mellon University could one day change all that.

Instead of relying on a bog-standard bulb to beam light out over a darkened road, the futuristic setup would use something more akin to a projector. Meanwhile a camera sits nestled beneath that projector, keeping an eye on drops of rain as they enter the headlights’ beams. Information from that camera is sent to a processing unit, which identifies raindrops and makes a guess as to where each droplet is headed.

The projector then blots out the bits of its projection where the rain drops are. The result is a light that shines out from the front of a car in the dark, but doesn’t highlight any rain.
