| Abstract: | A multiobjective optimization based emission spectral tomography algorithm(EST) is proposed. Its reconstruction results for asymmetrical emission coefficient field are studied by numerical simulation with computer. The results show that this algorithm has faster convergences and higher reconstruction precision than that of traditional algorithms and is suitable for real time reconstruction of emission coefficient field with incomplete data. In the experiment of argon arc plasma diagnosis, the three dimensional reconstructions of temperature and atomic (ionic) density fields are accomplished with this algorithm and the spectrum relative intensity method. |
