copper plate image
Fig. 7 projects a copper plate image of an optical disk.
It’s a circular ring of 116 mm outer diameter and 41mm inner diameter.
From the video system we can quickly analyze a optical disc master plate
within 15 minutes using our new software algorithms. But if we adopt traditional
pattern classes and K-mean operation, it will take 14 hours to complete
an optical disc.
