Heterodyne and quasi-heterodyne holographic techniques are being used to great advantage in steady-state full field contouring and deformation studies, for example. The high dynamic range and sensitivity afforded by these techniques is also of benefit in high speed holographic applications where there is the potential for providing new holographic tools to study a variety of high speed, transient phenomena. Full field visualization of surface acoustic waves, surface perturbations from acoustic emissions, and deformation during dynamic fracture studies are but a few of the potential applications of high speed heterodyne hologram interferometry. Triple-exposure and high speed switching techniques have been developed to facilitate recording of pulsed holograms for subsequent heterodyne analysis. Additional modifications to more conventional CW recording and readout geometries have been explored as well. Some degradation in sensitivity results from increased spatial and temporal noise associated with high speed recording.
