Paper Abstract

Local material insufficiencies on or near the object surface lead to locally high dense fringes at the displacement and shape measurement by holographic interferometry and TV- holography. In such case cutting out fringes results in relatively easy interpretation of the remaining interference pattern and identification of the defect. Fringe compensation techniques are widely used for eliminating the background fringes. The paper proposes a compensating technique based on phase-shifted interferograms. Its principles and applications are presented.
