Spectroscopic measurements on 3D objects in thermal plasmas

3D models developed for improving industrial applications and characterizing plasma medium, need to be validated by experimental developments. Nevertheless, spectroscopic measurements on 3D plasmas are very complex and consequently, until now, there is a lack of experimental results. We developed an experimental 3D plasma characterization based on tomographic method. The principle of this method is presented in this paper with the corresponding experimental setup that we performed. We also give some preliminary results.
