Paper Abstract

In this paper, we propose a method to detect the valid phase pixels of fringe patterns obtained with phase shifting interferometry. From a set of simulated interferogram images, we obtain a set of equations to discriminate between valid and invalid wavefront phase pixels, which allow us to compute the wavefront aberration. This method is useful for testing any converging optical system in a quantitative way with either a small or large focal ratio, with either polished or rough surfaces and with wavefront or lateral shear interferograms.
