A raster input scanner for reading documents typically consists of an illumination source, a collection optics using a lens, and a linear imaging array. The linear imaging array provides the scanning in one direction whereas the document motion provides scanning in the other direction. The lens images the document on the imaging array and one or more mirrors may be used to fold the optical path.
