Methods for Reconstructing Spatial Distributions of Radiation from Plasmas.

摘要

Methods are discussed for reconstructing spatial distributions from two types of projection -in a direction tangential to a torus and in a cross-sectional plane. For a tangential projection the reconstruction is unambiguous. For cross-sectional projections one usually does not have enough information for an unambiguous reconstruction,unless strong simplifying assumptions are made. A method is given for fitting a spatial distribution to such projections. Tests of both methods are discussed. The fitting method for cross-sectional projections is compared with a Fourier-series method. (ERA citation 04:047898)
