Abstract
Optical transport parameters (transport propagation length of radiation and scattering length) have been experimentally studied in samples of a foamed liquid for a wavelength range of 500–900 nm. On the basis of the obtained experimental data, the values of the anisotropy parameter of light scattering in a foamed liquid are found as a function of the aging time. It is concluded that the values of the scattering anisotropy parameter close to zero in the early stages of aging are due to a strong correlation of the spatial positions of the scattering centers (gas bubbles in the liquid-phase matrix). The increase in the scattering anisotropy parameter with aging of the foam is due to “optical” inversion (a transition from the regime of light scattering by gas bubbles in a liquid to scattering by regions of intersections of the foam cell boundaries in a gas matrix medium).
