Paper Abstract

The optical diffraction by fractal openings is increasingly being studied, because it allows to determine the properties and parameters that characterize these objects. Allain and Cloitre published the first results showing that the resulting analysis of the distribution of intensity obtained for diffraction experiments through fractal deterministic pupils permits the direct objection of the Hausdorff dimension an of other geometrical characteristic of these structures. In this work are studied, solved analytically, and characterized the lacunarity effect (epsilon) , dimension d and stage of growth k of Cantor fractal about he distribution of intensities of the diffraction pattern. In particular we make notice in the influence of lacunarity because this is one of the first works in which this geometric fractal parameter is being into consideration. The result of this study allow to say that an intimate relation exists between the distribution of the diffracted waves and the parameters that describe this kind of fractal geometry.
