英文摘要: This paper presents a technique to diagnose the three-dimensional temperature fields of arc plasma with orthographic and double-wave spectral tomography. First, the system with two orthographic directional CCD image real-time cameras is adopted to get the information of spectrum intensity related to the gray scale of arc plasma. Second, the improved computerized tomography iterative technique which accords with the least-square and max-entropy criterions, simultaneously, has been used to reconstruct the distributions of different emission coefficients, which shows superiority to the conventional tomography algorithms. Finally, based on plasma physical theory, the spectrum relative-intensity method has been used to reconstruct the distribution features of three-dimensional temperature fields. The experimental results have shown the effectiveness of this measurement system with high-precision and real-time ability. (C) 2009 Elsevier Ltd. All rights reserved.
