Holographic Interferometry In Fourier Plane Using Digital Image Processing
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).
