    Abstract: An apparatus for cleaning an optical surface, at least a portion of the surface being covered by an optically transparent liquid film, includes a wiper including an edge extending across at least a portion of the optical surface and urged into close proximity with the optical surface, the edge being defined between a leading face and a trailing face. The apparatus also includes an actuator operable to move of at least one of the wiper and the optical surface to cause the wiper to traverse the optical surface such that the leading face dislodges contaminants entrained in the liquid film or adhered to the optical surface to produce a cleaned portion of the optical surface. The apparatus further includes a liquid applicator disposed behind the trailing face of the wiper and operable to dispense liquid for renewing the liquid film on the cleaned portion of the optical surface.

    Abstract: Embodiments of the present disclosure address problems presented by contaminants, such as dirt and debris, by providing an optical apparatus with techniques and methodologies for self-cleaning. In that regard, embodiments of the present disclosure employ techniques and methodologies for maintaining a very thin (e.g., few microns thick) layer of liquid, such as a non-stick liquid, on an optical window of an optical body that shields or protects an optical device.
