| Description |
or analysis of the dynamics of forced and spontaneous transitions, a parametric 3D model of the black body radiation spectrum is proposed. Its orthogonal projections are the first and second-order signatures, in the configurations of which dynamic, energy and information aspects of the spectrum of thermal radiation are displayed. Their comparative analysis revealed significantly greater sensitivity of the parameters that reflect the dynamics of radiative transitions to small changes in temperature than the parameters of thermal radiation (r*(λ T), R), which are used in optical pyrometry. It is shown that the influence of external factors on the dynamics of physical processes in crystalline boule is most evident in 3D models of the functional characteristics of the samples. The structure of the functional characteristics of the samples from crystalline boule contains information on the features of defects formation. It is shown that for the effective growth control, interrelated parameters characterizing the features of the dynamics of radiative heat transfer in a growth furnace are needed. The expansion of the number of interrelated parameters that reflect the dynamics of radiative heat transfer makes it possible to carry out the effective parametric control of crystal growth.
