Abstract
The method of wavelet analysis is used to study fluctuations in the intensity of laser radiation scattered from interphase boundaries in the layer of a porous medium (paper) during evaporation of a volatile liquid with which the layer was impregnated. The analysis was performed using the Morlet wavelet as the base transformation function. The obtained wavelet spectra reflect characteristic features in the development of the evaporation front that correspond to various stages of the process of nonstationary mass transfer in the porous layer-volatile liquid system studied.
