Plasma jet radiation was recorded by a high-speed CCD camera from three directions separated by angles of 120°. We have taken two types of records; one at low resolution of images and very high frequency of recording and second one with high resolution and lower frequency. We observed the behavior of plasma jet radiation by changing axial and tangential flows. For the three dimensional reconstruction of palsma jet we developed a method basedon tomographic principle using inverse Radon transformation (IRT). Reconstructed three dimensional record was compared with the original two dimensional measurements. Accuracy and correctness of reconstruction was examined depending on the resolution of input informationand IRT type.
