Paper Abstract

In the paper the results of experimental researches of parameters of a laser beam passed through a convective column shaped above a zone of shining wood materials have been shown. Estimates of structural characteristics of temperature fluctuations C(Tau )2 and refractive index Cn2 determined from measurements of temperature gradients at the altitude 105 cm have been presented. The root-mean-square deviations of fluctuations of the image of a divergent laser beam measured are compared with ones calculated on Cn2 taking into account profile of temperature in the convective column. The spectra of fluctuations of the image and intensity of a divergent laser beam have been determined also. It is shown that the turbulent parameters in a convective column since some altitude corresponds to conditions of a free convection.
