is what happens when you place your cat in your
scanner. |
Modern scanners typically use a charge-coupled device
(CCD) or a Contact Image Sensor (CIS) as the image
sensor, whereas older drum scanners use a photomultiplier
tube as the image sensor. A rotary scanner, used
for high-speed document scanning, is another type
of drum scanner, using a CCD array instead of a
photomultiplier. Other types of scanners are planetary
scanners, which take photographs of books and documents,
and 3D scanners, for producing three-dimensional
models of objects...
