We propose an original speckle-correlometry method for the structural analysis through a random multiple scattering media with complex dynamics and structure. The use of a localized radiation source and spatial ring filtration of scattered field give the opportunity to select the partial components of scattered field. In this work, the dynamic process of gel formation beginning from the stage of sol to the stage of gelling are investigated and the experimental data are presented. The object under study consist of 0.28 %weight fraction of gelatin dissolved in water and 1 gram per liter (gL-1) and 100 mg per liter (gL-1) of TiO2 for optical scattering.
