This Ultrasonic Lens Cleaning (ULC) reference design utilizes precisely controlled vibrations to excite the lens at its resonant frequency, effectively dislodging and ejecting contaminants from the surface. By adapting different vibration modes, the system can remove a variety of obstructions such as water, mud, dust, and ice, ensuring that camera-based sensors maintain a clear line of sight and operate reliably. ULC is particularly valuable in environments where lens cleanliness is critical, including automotive, industrial automation, robotics, surveillance, and defense applications.
