Paper Abstract

Rapid development of reliable high power lasers, of an instant processing of photothermoplastic film and of a computer based fringe interpretation system enables the application of holographic interferometry in industrial environment. Holographic interferometry offers some essential advantages - non contact, inertialess measurement - the object is not affected - 2-dimensional image like information - testing under practise related loading - relevance between holographic indication and actual flaws The key for industrial application is a computerbased fringe interpretation.
