Abstract: An apparatus for protecting an optical device from contamination is disclosed. The apparatus includes a window disposed between the optical device and a contaminating environment, the window being rotatable about a rotational axis and including an outwardly facing surface that is curved in at least one direction about the rotational axis. The apparatus also includes a bezel enclosing a portion of the outwardly facing surface and defining a clear aperture for transmission of electromagnetic radiation to or from the optical device. The bezel includes a seal extending around a periphery of the clear aperture and is configured to cause the seal to conform to the outwardly facing surface when the window and bezel are urged into contact with each other. The apparatus also includes an actuator operable to cause relative rotation between the window and the bezel to cause the outwardly facing surface to move with respect to the bezel. The apparatus further includes a seal configured to dispense a film onto a portion of the outwardly facing surface that enters the clear aperture during the relative rotation, the film being operable to reduce bonding of optical contaminants to the outwardly facing surface within the clear aperture while transmitting the electromagnetic radiation to or from the optical device through the clear aperture. The seal is configured to dislodge contaminants entrained in the film or adhered to a portion of the outwardly facing surface moving out of the clear aperture during the relative rotation.

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.
