title: Three-dimensional deformation field measurements with simultaneous TV holography and electronic speckle photography.
abstract: The ordinary recordings of TV holography (phase-stepped electronic speckle interferometry), arranged for out-of-plane sensitivity, are recombined and also analyzed by use of electronic speckle photography for simultaneous measurements of all three components of the deformation vector field. The principles of this technique are presented. Experimental results showing the opening of a slot in a perspex plate are also presented.
