Imaging sensor air shield

Abstract

A detection device is equipped with a system to deliver pressurized fluid or compressed air or both to a lens or other optical surface to prevent or mitigate damage caused by the impact of debris. The detection device uses its own image detection function to track the trajectory of an object that might strike and impact the detection device. The detection device activates a burst of pressurized fluid or compressed air or both to shield or mitigate damage from impact. The detection device includes a housing, at least one surface mounted to the housing, and a spray device mounted to the housing. A medium, such as a liquid, gas, or compressed air, is selectively sprayed by the spray device. The spray device is activated to spray the medium when an object is approaching the surface, such that the trajectory of the object is altered when the object contacts the medium.
