Abstract
A device for detecting a soiling of a transparent cover of at least one transmitting window and/or one receiving window of an optical sensor. The device includes at least one hologram structure, an image sensor, and a processing unit. The at least one hologram structure is designed to at least partially deflect light beams incident through the transparent cover, or light beams reflected by an inner side of the transparent cover, in the direction of the image sensor. The image sensor is designed to detect at least one image signal as a function of the deflected light beams, and the processing unit is designed to detect a soiling of the transparent cover as a function of the at least one detected image signal. An optical sensor including the device, and a method for detecting a soiling of the transparent cover, are also described.
