Speckle patterns produced by computer simulations on the assumption of a power-law illumination of scattering objects are investigated on the basis of multifractal analysis. This analysis provides us with more detailed information on a fractal structure than conventional methods yielding a simple dimension. To examine multifractal properties of simulated speckle intensities, their generalized dimensions and singularity spectra are calculated by means of the method of moments. The results show that the multifractal description of the speckles characterizes clustering behaviour of the speckle intensities.
