An Application of Holographic Interferometry to Evaluate the Dynamics and Material Characteristics of Cast Compliant Structures

  • Howard Fein

Abstract

Holographic Interferometry techniques have been succesfully employed to characterize and test the behavior of materials in structures under stress1,2,3. These techniques are especially suited to investigating the dynamics of the material volume and the efficacy of bonds at the interfaces of different materials in bonded and cast compliant structures. Such structures are characteristic of systems in which arrays of active transducers are used to modify the surface or geometry of the structure, such as in active optical systems and acoustic sonar arrays. Knowledge of the causes and effects of structural anomalies and defects is of critical importance to insuring correct operation.
