Foggy conditions are a prevalent concern when it comes to transportation. In a fast moving vehicle, fog can conceal the path ahead and obstacles that may be in the road, making it a matter of safety. Foggy weather is also one of the most frequent causes for public transportation delays and cancellations.
The reason why fog obstructs vision is because it is made of water droplets which scatter light which we need to see forward. Once he identified the source of this problem, Guy Satat invented All Photons Imaging. This device leverages the scattered light paths created by fog and reconstructs the image the driver would see without fog present.
