Abstract
A laser-based displacement detector is used to detect cosmetic coatings applied to one surface of the transparent article and thereby determine which side is uppermost when loaded into the laser processing system. In particular, articles that are transparent to visible light and are particularly difficult to orient properly in laser processing systems are oriented using a laser-based displacement detector in conjunction with a partial coating on the article.
