BioNews While driving in the rain, or when there is snow fall,
visibility sometimes gets worse when the headlights are on. How
would be if headlight beams could bend around the raindrops so
that the driver can see what’s ahead of them. Now, a team led by
an Indian origin researcher has found a way to do just that. By
not illuminating the raindrops the headlights would avoid a
common problem: in heavy rain, headlights make it harder to see,
not easier. Headlight beams reflect off the rain (or snow, or
fog). The reflected light heads back to the driver’s eyes, not
to the obstacles on the road. The protoype system, developed by
the Carnegie Mellon University team led by Srinivasa G.
Narasimhan, consists of a camera, projector, and beam splitter,
linked to a computer processor, Discovery News reported. The
camera takes a picture of the raindrops at the top of the field
of view. The processor c
