Abstract

The usual holographic interferometric techniques do not make it possible to compare the deformations or the shapes of two similar but different objects in direct interferometric way. The DHI technique overcomes this limitation by using holographically reconstructed illumination wavefronts in the usual holographic interferometric techniques. Experimental results have proved the applicability of the technique in both the deformation and the shape measurements. Although many practical problems are to be solved yet DHI can be expected to become a routine control measurement in an assembly line.
