Simulation of Saddle-Shaped Optical Fringe Patterns

MATLAB simulation for generating saddle-shaped optical fringe patterns, including fringe orientation extraction, binarization to obtain coarse wrapped phase maps and centerline diagrams. These techniques provide significant guidance for phase unwrapping in Electronic Speckle Pattern Interferometry (ESPI) and Radar Interferometry (INSAR) applications, employing gradient-based orientation calculation and morphological processing algorithms.
