In Brief

Researchers from Carnegie Mellon University and Intel are developing smart car headlights that can cope with precipitation.

Researchers from Carnegie Mellon University and Intel have developed a prototype smart headlight system that can cope with raindrops and wind-blown snowflakes. The system, which has been tested during a snowstorm in Pittsburgh, uses a projector, camera and 50/50 beamsplitter.

The path of the particles is tracked and their future locations are determined so they can be dis-illuminated and the headlight beam only shines light around the precipitation. Standard vehicle headlights tend to illuminate raindrops and snowflakes, making them appear as bright flickering streaks that are distracting to the driver.
