Wavefront recovery in shearing interferometry with variable magnitude and direction shear

Abstract

We propose a regularization method for estimating the wavefront from shearing interferometric patterns generated in vectorial shearing interferometry. The method considers shearing patterns with variable magnitude and direction displacement. This regularized technique leads a stable solution of the inverse shearing problem and allows the reduction of the wavefront noise. We present the results of this technique applied on synthetic shearing interferograms.
