The new features of HDI 9 include a new generation of high-speed, low-noise Complementary Metal-Oxide Semiconductor (CMOS) cameras to deliver up to 80,000 images per second. These cameras yield high resolution images of the web process to capture every passing defect with previously unseen detail.

ABB’s new imaging hardware is complemented by new signal processing electronics to process and analyze the data in real time to categorize defects of all sizes using patented vision algorithms. For instance, the detection method includes several processing phases where the whole 12 bit dynamic range of sensors are utilized to reveal the smallest and lowest-contrast defects.

The HDI 9 system supports a variety of different web imaging geometries and high intensity illumination options using the latest LED technology to bring superior stability and measurement robustness for all applications.
