Abstract (en)
[origin: WO2022058545A1] Method for keeping clear a viewing region through a transparent element (10) of an optical monitoring device (100), comprising the method steps of: - forming an uninterrupted film (50) of a liquid on the transparent element (10); - coupling ultrasonic waves (64) into the transparent element (10), thereby helping contaminants (70) and/or residues left attached to the transparent element (10) to be dislodged by the ultrasonic waves (64) coupled into the liquid film (50) and/or the transparent element (10).
