Paper Abstract

In this work, we obtain an analytical expression for the relationship between the frequency transference functions of a 2D image formation system and a tomographic system, both with spatial filtering, in order to visualize phase object slices. We show the possibility to synthesize 2D filters, with 1D ones, and also present some numerical examples. The cases of coherent and partial coherent illumination are covered, the last one just for thin phase objects.
