Application of diffraction tomography to plasma density measurements (invited)

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.
