Paper Abstract

Holographic Interferometry has been successfully employed to characterize the materials and behavior of diverse types of structures under stress. Specialized variations of this technology have also been applied to define dynamic structural behavior. Such applications of holographic techniques offer some of the most effective methods of structural analysis and flaw identification available. This technology is nondestructive, real-time, and definitive in allowing the identification of structural and mechanical geometry as well as describing dynamic behavior under stress. Structures and materials can be analyzed with very low amplitude stress or excitation and the resultant data can be used to adjust the accuracy of mathematically derived structural models or as criteria for complete inspection and analysis programs, as well as in developmental analysis.
