Abstract
The fractal dimension of an object may be determined through the relation M(r)=rD between its mass M and its radius r or the pair correlation function g(r)=rD−d (d is the dimension of the euclidian space embedding the object). Yet, it is possible to have access to the value of D when studying the variation of the intensity I(q) which is scattered by a fractal at a wavevector q: I(q)=q−D. This relation has been used to interpret several small angle scattering experiments on silica (1). In this paper, we discuss diffraction experiments on deterministic fractal gratings (F). The intensity I(q) at wavevector q is the Optical Fourier Transform (OFT) of the grating F. This allowed a direct determination of D and led us to take in account other geometrical caracteristics of fractals.
