Optical scanning system

A scanning system can be an input or output system or a combination of both.  A system’s imaging fidelity depends on and begins with the reading of the input information and ends with the writing of the output data.

Optical scanning can be defined as a system articulation of light to provide information transfer.

An optical scanner is a digital computer input hardware that captures a bit-mapped image of a document.

When the image scanned is a photograph, it may be stored for use as is or be subjected to image processing.

It can read text and graphics from printed material.  A scanner works by digitizing an image – by digitizing it into a grid boxes and representing each box with either a zero or a one, depending on whether the box is filled in.

Optical scanning serves as an information converter. It transforms a spatial function such as images into a time domain to adapt it to electronic processing.
