Abstract:The electron density in the solar atmosphere maybe tomographically reconstructed from a series of remotely sensed observations of the white-light corona measured at distinct points-of-view. Measurement noise and the sparsity of available measurement points-of-view prohibit the use of classical tomographic reconstruction techniques and demands statistical methods utilizing prior information for successful reconstruction. This thesis formulates the reconstruction as a linear inverse problem and discusses robust, regularized, positive estimation as a potential solution. Numerical experiments demonstrate the effect of regularization parameter on the qualitative and quantitative fidelity of a simulated tomographic example.
