Abstract

This paper describes a Pin Hole Detector designed for small surface defect detection on a mirror finish high density magnetic disk using an industrial television camera. In this system, the utilization of a silicon vidicon is successful for the line scanning method. ITV function for detector and image monitor contributes to system simplification and has various advantages in laboratory usage. For study convenience, inspection results are printed out in a list on a mapping form, indicating defect location and demensions. Detected defects are automatically aligned on the TV monitor view field, when this monitor is used for visual inspection, after specifying the desired data input through the teletypewriter unit.
