Abstract: (3214 Views)
In this paper we propose a new and efficient method to simultaneously reconstruct two unknown interfering wavefronts. A three-dimensional interference pattern is analyzed and then Zernike polynomials and the stochastic parallel gradient descent algorithm are used to expand and calculate wavefronts. As one of the applications of this method, the reflected wavefronts from two surfaces of a spherical lens are experimentally reconstructed.
Keywords: Interferometry, Wavefront reconstruction
