Abstract: This disclosure relates to systems and methods for ultrasonic lens cleaning. In an example, an ultrasonic lens cleaning system can be configured to apply sequences that include at least one driver signal adapted to drive a transducer adaptively coupled to a top cover. The transducer can be excited based on the sequences to vibrate the top cover to remove a contaminant from a surface of the top cover. The applying of the sequences can include applying a first sequence to the transducer based on a first set of sequence parameters, applying a second sequence to the transducer based on a second set of sequence parameters, and applying a third sequence to the transducer based on a third set of sequence parameters.
