Intelligent Headlights Make Raindrops Disappear
• Colin Lecher via PopSci.comAnyone who's ever driven through a heavy rain has hoped for something like this: a system that can make rain drops vanish--or at least look like they do.
Intel and Carnegie Mellon University have developed technology that makes it happen, CNET reports. Each headlight projects not just a single beam, but a grid of several tiny beams (that's how the different-colored pixels are projected on the screen when there's actually an image being shown).
A camera behind the projector watches for raindrops, and a processor predicts their paths. Then the projector blocks out just the part of the grid where the rain is falling, darkening just the pixels in its way. Presto: a rainless view.
