Abstract

The holographic interferograms in Fourier plane are characterized by the fact that the fringes are always localized in the hologram (Fourier) plane and occur in two patterns only: stright parallel or circular lines. Thus, measuring the decentering, tilting and spacing in the'fringe pattern, it is possible to obtain simultaneously all components of the displacement/vibrations amplitude vector from one hologram1). Taking into consideration these advantages, a hybrid holographic-digital processing system for 3D displacement measurement was developed2).
