Scanners: softening up hard copies
Article Abstract:
Scanners use illuminate the original image, then using mirrors and lenses, reflect the image into an array of charge coupled devices. These convert the various light intensities to voltages, which in turn pass through a chip, where they are changed to the 1's and 0's that computer software understands. Flatbed scanners remain the best means of scanning a wide variety of originals. Sheet-fed scanners are more compact, but for the best reproduction, the original document is limited to sheet-size. A typical scanner costs $100. Most scanners sold today are purchased for home use.
