The paper presents a method simplifying the photographically registered interference fringe contours or profiles. The classical, commonly used, laboured and time-consuming method of fringe profile photometrical evaluation is replaced by a method of processing, based on the Sabattier effect reducing the interference fringes to equidenses - locuses of points of maximal density (of "blackening"). The described method substantially speeds up the interference fringe evaluation and might be useful also in cases when due to poor quality of the recorded interferogram, other methods of evaluation are in practice inapplicable.
