Thermal plasma produced by plasma torches is both a dynamical system challenging for analysis and a reactive matter with high energy density used in many industrial applications. With the help of mirror system, we have recorded plasma jet, produced by the experimental DC plasma torch, simultaneously from three directions. Tomographical reconstruction of 3D evolution of plasma radiation using previously developed method of interpolated profiles followed. Finally we used wavelet analysis to compare fluctuations of plasma for different variants of gas input. Reconstructed images of plasma radiation and fluctuations are presented.
