In any work environment utilizing computer systems, scanners also play a vital role.
These utilities provide the services of enabling to get scan any hard copy format entity into a soft copy format into the computer system (scanner).
With a basic understanding of what a scanner is, it is appropriate now to have a view at the technical aspects.
According to theoretical language, scanner have the ability to optically scan images, text, handwriting or an object and convert it to a digital image.
There are two main variations or types of scanners available today.
One being the desktop or flatbed scanner and the other being the hand held scanner.
In a flat bed scanner, the document to be scanned is placed on the glass window type area for the scanning to be performed.
In a hand held scanner, as the name suggests, the scanning is performed by moving the device by hand.
With respect to modern times, scanners have evolved to a great extent.
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.
