A general phenomenological approach - a Flicker Noise Spectroscopy (FNS)- to revelation of information valuable parameters characterizing the arbitrary chaotic surfaces was develop to distinguish their patterns and describe quantitatively their functional properties. The consideration was carried out in terms of correlation lengths and additional parameters characterizing the rate of correlation links lost in the sequences of surface irregularities. The parameters are obtained by fitting the Fourier spectra and structural functions (difference moments of different orders) calculated for the digitized surface profiles using the approximations derived on the base of model representation of the profiles as the sequences of irregularities of different types (“bursts”, “jumps”, etc.). The method developed was applied to revelation of effects of a shungit filling agent in polypropylen matrix on the composite properties, revelation of hydrogen treatment effects on the cleavage surfaces of LiF monocrystals after their dissolution in water with quantitative evaluations of their anisotropy, analysis of activity of vacuum deposited porphyrins layers in a photosensibilized gnenration of singlet oxygen into gaseous phase. The approach elaborated can be used for developing the new control tools in nano-technologies, microelectronics, production of polymeric material with the specific surface properties, and others.
