Verfahren zum Detektieren von Produktionsfehlern in einem Artikel

摘要

Manufacturing errors in an article are detected by comparing an image of the article with a theoretical image generated by a computer aided drafting system and identifying any differences between the two.The images may be video images, photographic images, holograms or constituted by data held electronically. A laser interferometry fringe pattern is formed representing the shape of the article and compared to an ideal interferometry fringe pattern generated by software linked to the CAD software.
