Abstract
An apparatus providing the capability to scan transmissive media is presented. The apparatus comprises an illuminating lid for an optical scanner. The lid is hingeably attached to the base of the scanner and provides a backlight for transmissive media. A light source, located within the lid, projects light through a translucent screen, through an X-ray for example, onto photodetector arrays located within the base of the scanner. Control means are provided to maintain the light intensity of the light source located within the lid so that a flat light profile is provided during the scan.
