Paper Abstract

Image processing has been used to analyze TV -holographic fringe patterns of deformations and vibrations. The processed pictures give improved detection and information for the operator of the interferometer. A lower detection limit of about ?./50 for deformation analysis has been achieved, while amplitudes down to V500 and phase values with an accuracy about 3° have been measured on vibrating objects. Examples of applications of the techniques are shown.
