Abstract

We report the experimental verification of an alternative method to the conventional least squares fit method for obtaining the phase of real interferograms, making an automatical polynomial fitting on exprimental data in accurate form. The process can be realized solving an optimization problem using an evolutionary algorithm, where the solution to the irradiance equation should be considered like an inverse problem and an objective function should be minimized. In this work we review the fundamental concepts comparing the performance of the least squares fit method and the evolutionary algorithm used in the experimental interferogram analysis.
