Abstract

A new technique that exploits physical constraints for improved accuracy in volume reconstruction of the terrestrial plasmasphere´s plasma density is presented. The goal of the work is to support volume reconstruction given a small number of 2D external views from locally close viewing positions. The technique is aimed at allowing exploitation of time-series 2D image data from the EUV sensor on NASA´s IMAGE satellite. Reconstruction quality benchmarking results on synthetic data are also presented.
