The scanning detection system for a narrow crack on a ceramic plate has been developed. When a laser spot is illuminated on a ceramic plate, the laser is diffused within the ceramics and interrupted by the crack. The crack is detected automatically by detecting the difference of irradiants on each side of crack. In the experimental apparatus the laser spot is scanned with a polygon mirror and the distribution of irradiant on the ceramics is detected with a 2-divided photodiode. The high sensitivity for crack detection is obtained using a finite difference value of detected signal. Experimental results show that this crack detection technique detects the cracks of 0.5μm at an S/N ratio of 2 in the scanning process of laser spot.
