Fringe pattern simulation with a adaptive pendulum

Benem´ erita Universidad Aut´ onoma de PueblaFacultad de Ciencias F´ šsico-Matem´ aticas(Dated: August 24, 2011)In this work we propose the simulation of a fringe pattern in analogy with aoscilating pendulum with adaptive parameters. This technique will be used in futureto recovery the phase of interferograms by mean a dynamical model.We reproduce a reference fringe pattern solving the dynamical model of a pen-dulum with adaptive length parameter, by computer simulation. We obtained goodpreliminary results with this dynamical system. The dierential equation was sim-ulated with Simulink Toolbox of MAT LAB. We show our results.Keywords - Adaptive Dynamical System, Simulated Fringe Pattern, VariableFrequency Oscillator.I. INTRODUCTION
