An image scanner—often
abbreviated to just scanner, although the term is ambiguous out of context
(barcode scanner, CT scanner etc.)—is a device that optically scans images,
printed text, handwriting or an object and converts it to a digital image.
Commonly used in offices are variations of the desktop flatbed scanner where
the document is placed on a glass window for scanning. Hand-held scanners,
where the device is moved by hand, have evolved from text scanning
"wands" to 3D scanners used for industrial design, reverse
engineering, test and measurement, orthotics, gaming and other applications.
Mechanically driven scanners that move the document are typically used for
large-format documents, where a flatbed design would be impractical.
