Abstract
A scanner includes an illuminator and a platen adapted to support a document to be scanned. A light source directs light into the platen and the light is reflected internally within the platen. A movable light sensor is positioned adjacent the platen. Liquid crystal sections between the document and the light sensor cause a zone of light to pass from the platen to the document, thereby illuminating only a portion of the document.
