摘要
Disclosed examples include ultrasonic lens cleaning systems and driver circuits to clean a lens using four or more transducer segments mechanically coupled to the lens, in which the driver circuit provides phase shifted oscillating signals to the transducer segments to generate a mechanical traveling wave rotating around the center axis of the lens to vibrate the lens for improved ultrasonic cleaning.
