processing results


   Fig. 8 projects a series of microscope images of processing results during our experiments. These patterns prove that this system can quickly and efficiently detect the small defects of various types in an entire optical disc master plate. From the quantity of pitting defects, dust defects, smut defects, spotting defects, we can decide to pay the attention to contamination control or electro-forming process.
