Arrangement for and method of uniformly illuminating direct part markings to be imaged and electro-optically read |
摘要 |
Performance of an imaging reader for electro-optically reading direct part markings on workpieces is enhanced by uniformly illuminating the markings. An illuminator is operative for emitting illumination light of greater and lesser intensity toward the indicia. A diffuser is operative for diffusing the illumination light en route to the indicia. The diffuser includes a plurality of diffusing elements adjacent the illuminator for diffusing the illumination light of greater intensity more than the illumination light of lesser intensity.
