Abstract

Oppfinnelsen angår en fremgangsmåte og anordning for ikke-destruktiv testing av detaljer, maskinenheter og mekanismer, forskjellige materialer, and særlig en fremgangsmåte og anordning for ikke-destruktiv bestemmelse av egenspenninger som er basert på den optiske holografiske interferometriteknikken. Først registreres et hologram av undersøkelsesområdet av objektet i sin starttilstand. Deretter gjennomføres frigjøringen av egenspenningene i et undersøkelses-punkt i undersøkelsesområdet ved eksponering av overflaten av objektet til en høy-strøm elektrisk puls med rektangulær form. Til slutt lages et interferogram av det nøyaktig samme området av objektet, og egenspenningene ved undersøkelsesområdet bestemmes fra formen og størrelsen av kantene i interferogrammet.
