Paper Abstract

The recent introduction of pulsed lasers for studying transient phenomena by means of TV holography makes very difficult the analysis of fringe patterns by conventional techniques. For this reason, previously to the evaluation of the phase distribution, digital filters must be applied to reduce speckle noise. In this paper some after fringe generation techniques for speckle noise reduction are compared: three methods commonly used in synthetic aperture radar imagery, a scale-space nonlinear filter and a de-noising method based on the use of wavelet transforms.
