3-D arc plasma fields reconstructions with self-adaptive emission spectral volume tomography algorithm

A novel self-adaptive volume reconstruction technique (SVRT) based on multi-objective optimization was proposed. Its reconstruction results for asymmetrical single-peak emission coefficient field were studied with the numerical simulation of computer. The results show that this algorithm has faster convergences and higher reconstruction precision and has reconstructed asymmetrical single-peak emission coefficient field perfectly with only two views. In the experiment of Argon-arc plasma diagnosis, the 3-D reconstructions of temperature and ionization coefficient fields were fulfilled with this algorithm combining with the spectrum relative-intensity method.
