Abstract

We define an objective method to classify defects based on their visibility : If a sample is illuminated against a black background, the observer sees only the defects. Now we replace the black background by an other with finite luminance. Some defects will become invisible, others will still be seen. If we change the illumination on the sample, the threshold between "seen and not seen" defects will be changed. With one standard defect and the la,' of gradation of the object luminance, we can classify all macroscopic surface defects.
