Applied Holographic Interferometry as a Nondestructive Method for the Dynamic and Modal Analysis of an Advanced Graphite-Epoxy Composite Structure
Holographic Interferometry methods have been successfully employed to characterize the materials and behavior of diverse types of structures under stress1,2,3. Specialized variations of this technology have also been applied to define dynamic and vibration related structural behavior4. Such applications of holographic technique offer some of the most effective methods of modal and dynamic analysis available. Structures and processed materials can be analyzed with very low amplitude excitation and the resultant data can be used to adjust the accuracy of mathematically derived structural models.
