Abstract
The system has an optical scanning device formed of a plurality of pixel elements for providing a scan output signal representative of a scanned region of an object. The system has a reflector, an illumination source, a light compensator, and an object positioner. The reflector defines an ellipse. The object positioner disposes the object substantially near the major axis of the ellipse. The illumination source emits and applies light energy to the object disposed at a first focus of the ellipse. The light compensator, which varies the light energy emitted from the illumination source, has one or more dedicated pixels of the optical scanning device. The light compensator also has fiber optical transmitters that receive light transmitted from the illumination source and couple to the dedicated pixels, which are unavailable for receiving reflected light from the scanned region of the object.
