Scanning device for optical scanning of an object extended in an object's plane has a device to illuminate the object, a linear optoelectric sensor at a distance over the object and a lens

摘要

An illuminating device (4,5) illuminates an object (2). A linear optoelectric sensor (9) fits at a distance over the object. A lens (10) fits between the object and the sensor and projects an object area onto the sensor. The object and the sensor are moved in relation to each other and in a line parallel to the object plane so as to perform a linear optical scan of the object.
