Holographic interferometry is a usefi~l optical technique used for visual analysis ofthe microdefor- mations of test objects resulting from the applica- tion of internal or external forces. Applications of holographic analysis include: * Failure mode analysis associated with vibra- tional excitation, mechanical loading, and ther- mal or pressure stressing. * Delamination and crack detection. * FEM verification and boundary condition determination.
