Description

Holographic Interferometry has been successfully employed to characterize the materials and behavior of diverse types of structures under stress [1,2,3]. Specialized variations of this technology have also been applied to define dynamic and vibration related structural behavior [4]. Such applications of holographic technique offer some of the most effective methods of modal and dynamic analysis available. Real-time dynamic testing of the modal and mechanical behavior of aerodynamic control structures has always required advanced instrumentation for data collection in either actual flight test or simulations. Advanced holography techniques are alternate methods which show full-field behavioral data on the ground in a noninvasive environment [5]. These methods offer significant insight in both the development and subsequent operational test and modeling of advanced exotic metal control structures and their integration with total vehicle system dynamics. Structures and materials can be analyzed with very low amplitude excitation and the resultant data can be used to adjust the accuracy of mathematically derived structural and behavioral models.
