Abstract:

Double-exposure image-plane holograms made with a reference to object intensity ratio less than unity can be used to measure three dimensional displacements on nearly planar subjects. Holographic interferometry is used to determine the normal displacement component. Speckle photographic techniques are employed to obtain the in-plane components.
