Paper Abstract

Second-order statistics of phase are investigated by computer simulations for speckles produced by illuminating a diffuser by coherent light with a negative power-law intensity distribution. Under such an illumination condition, the generated speckles are known to show fractal properties in their intensity distributions, thus being called fractal speckles. The present study shows that the phase of fractal speckles, as well as of ordinary speckles, exhibits a self-affine property of the type of fractional Brownian motions.
