Abstract

In structural testing the determination of the dynamic structure response is one of the most important and difficult tasks. Double pulse holography interferometer has been widely used for analysis of the dynamic behavior of the structures. Recently PulsESPI techniques are increasingly used to replace conventional double pulse holography interferometer, not only taking over the main benefits of holography towards conventional measuring techniques, such as full field, non contact and sensitive, but also uses modern video and computer techniques for image capturing and processing. Recent developments have extended the capabilities of PulsESPI techniques to 3D measurement of dynamic structure response and modal analysis of vibrations.
