Abstract
A disclosed example of a sensing device includes an optical surface and an air curtain generator positioned around the optical surface. The air curtain generator has at least one nozzle operable to provide a continuous forced air region traveling away from the optical surface, thereby forming an air curtain around the optical surface that provides a debris barrier for the optical surface.
