Abstract
A sensor lens assembly includes a cylindrical sensor body including a lower surface, a sensor lens surface, and a side surface extending between the lower surface and an outer edge of the sensor lens surface, a sensor enclosed within the cylindrical sensor body and adjacent to the sensor lens surface, and a nozzle configured to deliver a fluid near a center point of the sensor lens surface. The sensor lens surface is concave and rotates relative to the side surface of the cylindrical sensor body such that centrifugal force causes the fluid to form a film on the sensor lens surface that acts as a barrier, cushion, and particle collecting medium on the sensor lens surface.
