Industry's first ultrasonic lens cleaning chipset enables self-cleaning cameras and sensors

Texas Instruments introduced the first purpose-built semiconductors with ultrasonic lens cleaning (ULC) technology, enabling camera systems to quickly detect and remove dirt, ice and water using microscopic vibrations.

Removing contaminants from camera lenses traditionally requires manual cleaning, causing system downtime, or the use of various mechanical parts that could malfunction. TI’s new ULC chipset, including the ULC1001 digital signal processor (DSP) and companion DRV2901 piezo transducer driver, features a proprietary technology that allows cameras to rapidly self-clear contaminants using precisely controlled vibrations to rapidly eliminate debris, which improves system accuracy and reduces maintenance requirements. The chipset offers designers a compact and affordable way to use ULC in a wide range of applications and camera sizes.

The ULC1001 controller includes proprietary algorithms for automatic sensing, cleaning, and temperature and fault detection without any image processing, making ULC technology highly adaptable to various camera lens designs. The chipset’s small form factor makes it possible to improve machine vision and sensing in a variety of applications – any place that a camera or sensor could get dirty (more info).
