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
