From: The first observation of 4D tomography measurement of plasma structures and fluctuations
(a) Axial dependence of the normalized amplitude of total emission fluctuations (f ≤ 20 kHz) and the cross-correction. (b) Fluctuation spectra of the total plasma emission at the axial positions of z = 0.35, 0.60, and 0.85 m. (c) Axial cross-phase, coherence, and the correlation length (lcor) with reference position at z = 0.60 m. The calculations are performed in the quasi-steady state (t = 0.32–0.50 s).
