Paper Abstract

A method based on a hybrid genetic algorithm is proposed to obtain the wavefront aberrations of a real interferogram. By solving an optimization problem, the proposed method fits a set of Zernike polynomials to the experimental data. The results show that, compared to a conventional genetic algorithm, the hybrid genetic algorithm not only improves the searching ability but also accelerates the convergence. The proposed method is robust to spatial variation of the illumination.
