ABSTRACT:
Performance of an imaging reader for electro-optically reading direct part markings on workpieces is enhanced by ensuring that such markings are read in the vicinity of an ideal, focused, target plane, and by enhancing the contrast of such markings. Calibration and self-calibration of the reader improve performance.
