  In a recently published paper (J. of Modern Optics 50 (9) (2003) 1477-1486) a
qualitative analysis of the moire effect observed by superposing two grids
containing Cantor fractal structures was presented. It was shown that the moire
effect is sensible to variations in the order of growth, dimension and
lacunarity of the Cantor fractal. It was also verified that self-similarity of
the original fractal is inherited by the moire pattern. In this work it is
shown that these Cantor moire structures are also fractals and the fractal
dimension associated with them is theoretically determined and experimentally
measured attending the size of rhombuses in the different orders of growth.
