Application of diffraction tomography to plasma density measurements (invited)

Abstract

Diffraction from plasma density irregularities can have significant consequences for the tomographic inversion of line-of-sight integrated measurements of the phase disturbance suffered by a probing beam. A new tomographic approach which takes account of diffraction from high-K refractive index structures is described. The relevance for multichannel interferometry measurements is demonstrated numerically and the technique is applied to the inversion of multichannel TEXT interferometer data. Show more
