Line scan cameras
Materials produced in a continuous roll or sheet, such as paper, textiles, film, foil, plastics, metals, glass, or coatings, are best inspected by line scan cameras. Line scanning offers unlimited pixels in the direction of a web's motion with zero smear even at high speeds, higher dynamic range, greater processing efficiency and much lower price/pixel.
The cameras we use in our web inspection systems have a resolution of 8192 pixels and max. scanning rates of 90kHz.
In applications where we need to detect very low contrast defects or inspect at very high speeds we may need to use TDI cameras.
