Abstract

The paper presents the use of phase-shifted electronic holography as a NDT tool, in particular using vibration stressing for detecting damage in a car door. After a short introductory description of this technique and of the most frequently used stressing methods used in testing, some of the criteria used in the localization and identification of defects are presented and illustrated with experimental results. Both material damage and assembling faults are detected by applying these criteria and by an adequate choice of the frequency range of excitation and of the optical setup parameters.
