Fringe pattern simulation with an adaptive pendulum

Abstract

In this work we propose the simulation of a fringe pattern in analogy with a oscilating pendulum with adaptive parameters. This technique will be used in future to recovery the phase of interferograms by mean a dynamical model. We reproduce a reference fringe pattern solving the dynamical model of a pendulum with adaptive length parameter, by computer simulation. We obtained good preliminary results with this dynamical system. The differential equation (DE) was simulated with Simulink Toolbox of MATLAB. We show our results.
