Well there are many types of a scanner all for different purposes but if u r talking about Image Scanner than
In computing, a scanner is a device that analyzes images, printed text, or handwriting, or an object (such as an ornament) and converts it to a digital image. Most scanners today are variations of the desktop (or flatbed) scanner. The flatbed scanner is the most common in offices. Hand-held scanners, where the device is moved by hand, were briefly popular but are now not used due to the difficulty of obtaining a high-quality image. Both these types of scanners use charge-coupled device (CCD) or Contact Image Sensor (CIS) as the image sensor, whereas older drum scanners use a photomultiplier tube as the image sensor.
Another category of scanner is a rotary scanner used for high-speed document scanning. This is another kind of drum scanner, but it uses 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, but this type of scanner is considerably more expensive relative to other types of scanners.
Another category of scanner are digital camera scanners which are based on the concept of reprographic cameras. Due to the increasing resolution and new features such as anti-shake, digital cameras become an attractive alternative to regular scanners. While still containing disadvantages compared to traditional scanners, digital cameras offer unmatched advantages in speed and portability.

I've actually purchased there DS2 white light scanner for our lab. We love it and its very automated with a click of a button it scans 18-23 areas. Very fast!!! The scanner has 2 cameras that allows it to scan deep areas and for sharp margin lines it has 2 high resoulution cameras and its an open system. Good Luck and I defiantly recommend them.
