Abstract
A method based on the computer analysis of electron microscopic images of the surface of porous anodic aluminas is described for deriving quantitative information about the mutual arrangement of cells and pores (mesoscopic structure). The developed package of programs is used to calculate dimensional parameters of a cellular-porous structure, the size distribution of the image objects, and the morphological functions of the radial distribution of cells/pores, which are analogs of the function of the radial distribution of atoms characterizing the short- and medium-range orders of atoms in amorphous materials. A quantitative analysis is performed for the first time using the method of pair functions, which was used earlier for identification of the atomic structure in amorphous films. The developed package of Spot Calculator and MFRD programs for processing electron microscopic images of the surface can be used to study the mesoscopic structure of not only porous aluminas but also any materials if characteristic features can be distinguished on their surface.
