- 요약We present a new technique to tomographically reconstruct the density distribution of the solar corona and solar wind using near-perihelion data from the Wide-field Imager for Parker Solar Probe (WISPR). This technique, like traditional solar corona tomography methods, uses a set of different viewing angles to recover an additional dimension of information. However, unlike traditional tomography techniques, this method relies on the motion of the spacecraft -- Parker Solar Probe (PSP) -- to provide the set of viewing angles. Over the course of four chapters, we progress from an initial analytical inversion approach applied to a synthetic dataset, to a more robust `synthetic' inversion approach applied to real data from two different solar encounters. A change-of-basis operation via simple projection enables us to determine the model parameters that best support the features in the data. We also explore an application of this tool to coronal Faraday rotation experiments, specifically the determination of plasma density variations along the radio lines of sight. While this technique is not yet robust nor validated enough to yield new results about the structures themselves, it can provide complementary information to other observations. Finally, we have demonstrated that a tool like this has the potential to elucidate large-scale morphology and small-scale structure in the corona in the vicinity of PSP near perihelion passes.
