US Patent 11833978 Sensing system with sensor window having a superhydrophobic surface

A sensing system that includes an optical,sensor and a sensing window. The optical sensor is configured to sense with electromagnetic radiation an environment. The sensing window is coupled to a structure, such that the electromagnetic radiation passes therethrough from the environment to the optical sensor to be sensed thereby. The sensing window includes an inner side that faces toward the optical sensor and an outer side that faces away from the optical sensor. The outer side includes a superhydrophobic surface that is in fluidic communication with the environment.
