Abstract

An optical system for detecting the surface flaws of a molding, e. g., the brake disc of a car, has been proposed which involves a sheet-like laser beam of length, l, and width, w, as a probing light. Optimum conditions forthe sheet like laser beam were found to be l=10 mm and w=0.5 mm for a flaw diameter of 2 mm which is thesmallest diameter that can be detected in practice. The system consists of a sensor head including a lightsource and a light receiver, and a processing system including an amplifier, an A/D converter, a personalcomputer and a display. This system can detect all flaws in a few second by using a sampling frequency of dataacquisition at 1 kHz.
