Popis:	Flows in horizontal fluid layers with a free upper boundary with uniform heating from below are studied. With the use of thermal imaging scanning, the temperature fields on the free fluid surface in laminar and turbulent regimes of the Rayleigh-Benard convection are measured. Computer processing of thermal imaging movies makes it possible to obtain spatial-temporal characteristics of cellular and multiscale convective flows.
