Paper Abstract

The operation and behavior of arrays of active transducers comprising complex compliant structures depends on their true structural dynamics. Such structures are characteristic of control elements for adaptive optical systems, sonar system assemblies, and other continuously deformable complex compliant structures. The mechanical and physical interfaces between transducers and their supporting and radiating structures relate directly to their dynamics. Sophisticated bonding and processing of compliant and rigid materials in such complex assemblies determine their operational parameters. Understanding the effects of structural anomalies and defects is of critical importance to insuring correct array operation and a nondestructive method for the visualization of anomalous structural characteristics would be of great value in both development and testing of such systems. Also, mechanisms for acoustic energy transfer through these structures into adjoining media can be inferred from such visualizations. Holographic interferometry presents itself as a viable and useful method for the realization of this type of information.
