The development and effective implementation of new plasma technological processes based upon the method of dynamic plasma operation (DPO) under atmospheric pressure call for using the emission spectral tomography. To this end, on the basis of an experimental apparatus implementing the method we designed an automated emission spectral-tomography complex with the fan measurement system. We studied experimentally how the flow configuration depends on various plasma parameters. In the framework of the local thermodynamic equilibrium (LTE) model we reconstructed several cross-sectional profiles of spatial distribution of emission coefficients and temperature from the visible recombination continuum of the argon plasma flow of different configurations. We have developed a commercial model of emission tomograph for plasma technological installations.
