Paper Abstract

A new inspection system measuring micro-craters on a rotating laser textured dull roll surface has been developed. This system provides a video image of the rotating roll surface as a still vision using a stroboscopic light and a rotating mirror, and measures the diameter and the pitch of the micro-craters by an image processing method. The system can measure the pitch and the diameter of the micro-craters in the accuracy within ±10 mm errors when the circumferential speed of the dull roll is lOm/sec.
