Paper Abstract

A numeric algorithm for processing Newton's rings fringe patterns is presented. The interference images of this type have a characteristic appearance which can be described mathematically by a function depending on a set of parameters. The algorithm consists in finding the parameters of this mathematical expression by means of fitting the pattern using the least squares method, specially implemented with an iterative procedure. Unlike other processing methods which also use statistical calculus, this algorithm efficiently utilizes the whole information contained in the image and ensures the highest degree of accuracy, in given statistical fluctuation conditions affecting the image.
