Abstract
A system is disclosed in which a defect-indicating material is applied to the surface of a part which is scanned by a laser beam or by use of a television camera to develop electrical signals indicating defects. A comparison arrangement is provided for developing output signals only when signals are developed from the same portions of the scanned region during two scans, and a blower is provided for displacing extraneous elements between scans.
