Abstract
A vehicle and/or a method for detecting contaminants on an optical surface are provided. The vehicle includes at least one light source adjacent the optical surface and at least one light detector at an edge of the optical surface. A controller is configured to introduce light from at least one light source into the optical surface, and to measure light at the edge of the optical surface with at least one detector. The controller compares the measured light to a threshold, and, if the measured light crosses the threshold, triggers or implements a response action.
