Wavefront sensing using a graphical user interface

Abstract

We present an open wavefront sensor setup assisted with MATLAB programming to be used to teach the operating principle of Shack-Hartmann aberrometry. A new Graphical User Interface (GUI) has also been developed to determine the wavefront parameters from experimental measurements and the associated aberrations, which is a fundamental issue in Optical Engineering. From a didactical point of view, the proposed method allows students to interpret the results in a visual and heuristic way.
