Abstract: The paper considers results of an infra-red imaging study of the dynamics of change in the brightness-temperature field of surface forest fires in laboratory settings. The dynamics of certain characteristics (combustion-front velocity, flame size, total energy, etc.) and change in the brightness-temperature field are analyzed. The procedure of establishing a correlation between the thermodynamic and brightness temperatures is discussed.
