On reliability of 3D reconstructions of thermal plasma jet radiation by inverse Radon transform

摘要

Three-dimensional reconstructions of thermal plasma jet radiation were acquired by inverse Radon transform from records by a high-speed CCD camera from three directions separated by angles of 120°. The complexity of measured radiation profiles has been changed due to varying gas flow rates. Reconstructed three dimensional images of plasma radiation were projected back to individual detection planes and these projections were compared with the original two dimensional records. The complexity and accuracy of reconstruction were examined depending on the resolution of input information and parameters of the inverse Radon transform.
