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