Paper Abstract

This paper describes a method for the treatment of non- fullfield images by means of the Fourier fringe analysis technique. With this type of images, the borders of the data appear as high frequencies in the Fourier domain while the areas with the same intensity (background) appear as low frequency components. This information interferes with the signal peak and leads to large errors in the phase result throughout the image. This paper proposes a two dimensional mapping operation to overcome the problem. By a mapping of the original image into a square, the image can be processed by conventional FFA. The final result is obtained by the application of the inverse of the mapping function.
