AB  - A nondestructive flaw detection technique, based on a contactless device is presented. To demonstrate its applicability, measurements have been performed on several A1 plates before and after flawing them with one or more scratches. A spectrum analysis shows a significant change in the height of the odd harmonics, which increases with the number and size of the scratches.
