Submission + - Smart Automotive Headlight for Seeing Through Rain and Snow (

kelemvor4 writes: Standard vehicle headlights improve driver visibility at night by illuminating the road and the surrounding environment. Unfortunately, they also illuminate raindrops and snowflakes making them appear as bright flickering streaks that are distracting to the driver. We propose a headlight capable of avoiding precipitation to improve driver visibility while adequately illuminating the road. This reduces driver stress and makes roads more safe during rain and snow storms. We have conducted simulations and built a prototype system to show that the approach is feasible and effective. Demonstration of the prototype system with an artificial rain drop generator is encouraging making the falling rain disappear in front of the observer.
