Abstract

We have recorded in-plane displacements with speckle photography and out-of-plane displacements with holographic interferometry for solid bodies, from which the three- dimensional surface deformation can be determined. We demonstrate that it is possible to measure both uniform in-plane and out-of-plane displacements in one double-exposure hologram by reducing the reference-to-object-beam ratio to enhance speckle contrast in the hologram. We have also recorded the three-dimensional displacement of particles suspended in a fluid in a controlled experiment using holographic interferometry.
