The invention relates to optical surface contaminant detection. A vehicle and/or a method for detecting contaminants on an optical surface are provided. The vehicle includes at least one light sourceadjacent 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, triggersor implements a response action.
本发明涉及光学表面污染物检测,具体提供了一种车辆和/或一种用于检测光学表面上的污染物的方法。车辆包括与光学表面相邻的至少一个光源和在光学表面的边缘处的至少一个光检测器。控制器被构造成:将来自至少一个光源的光引入到光学表面中;以及用至少一个检测器测量光学表面的边缘处的光。控制器将所测量的光与阈值进行比较,并且如果所测量的光穿越该阈值,则触发或实施响应动作。
