Abstract

A fringe normalization procedure is presented in this paper. The main idea of the computer algorithm is to normalize the fringe pattern using spline interpolation functions. To achieve this, two splines are fitted using the maximum and minimum irradiance peaks detected over each fringe image line. Then, each pixel in the fringe image is interpolated and normalized by using of the values of the max and min splines. The fringe contrast is enhanced with an error around 1%. Preliminary results are presented.
