Abstract
A Fourier filtration algorithm has been applied to speckled fringe patterns, as obtained with the electronic speckle pattern interferometer. The Fourier power spectrum components found are then conveniently manipulated to extract noise that is inherent to the speckled fringes, thus rendering holographic-quality displays. The use of this technique facilitates the computer interferometric analysis of such fringe patterns. Some examples of the phase fringes and the corresponding object displacements obtained using this method are shown.Keywords
