Abstract

The surface morphology of a random powder typical of that used in powder diffraction is analyzed in terms of lateral second-order correlations and their variation with distance of a reference plane parallel to the surface. The experimental data are obtained from optical micrographs of subsequent focussing planes using suitable image analysis routines. The procedure turns out to be a non-destructive method for serial planar section analyses of rough surfaces.
