Contact image sensors challenge linescan cameras

摘要

High-speed web-inspection systems require high-resolution images to be captured by single or multiple linescan cameras that are deployed across the width of the web. With very high linescan rates, these cameras can capture images at high resolution across the transport width of the web. Because these systems are fast, they require cameras with very high sensitivity, a parameter only now being met by developers of high-resolution linescan cameras (see "Dual linescan imag-ers increase camera responsivity," p. 8).
