Abstract
Line scan CCD imagers have been used successfully in various applications such as remote sensing, document and film scanning, industrial inspection, and optical processing. However, high quality scanning of transparencies for electronic color separation has not been completely satisfactory when performed with CCD imagers intended for document scanning applications. This paper describes a new CCD imager specifically designed to handle the wide dynamic range of transparencies. This new line scan CCD imager features 6000 pixels 10μm x 10μm on a 10μm pitch. The 2.4 inch long chip is built on a low crosstalk substrate with all the state-of-the-art features: low-lag photodiodes, antiblooming and integration controls, output clock gates, in-phase outputs, and high scale factor amplifiers. The device is packaged in a new ceramic/precision metal header. A key performance parameter is its dynamic range: 30,000:1 (relative to RMS temporal noise in the dark, with CDS) which makes it an excellent candidate for use in high-resolution high-quality flatbed scanners.
