本文研究了弱相对论等离子体的干涉测量。结果表明，由于电子的相对论质量校正，等离子体和真空传播中的相位差变小。从通常的阿贝尔反演方程获得的轴对称密度分布也因校正因子而变小，对于 Te = 0 ∼ 60 keV，校正因子为 1 ∼ 1.3。结果表明，我们必须使用阿贝尔反演方程来考虑电子的相对论质量校正，才能重建正确的密度分布。
Interferometry for weakly relativistic plasmas is studied in this paper. It is shown that the phase difference in plasma and vacuum propagation becomes small due to the relativistic mass correction of electrons. The axisymmetric density profile obtained from the usual Abel inversion equation also becomes small by the correction factor, which is 1 ∼ 1.3 for Te = 0 ∼ 60 keV. It is shown that we have to use the Abel inversion equation to take into account the relativistic mass correction of electrons in order to reconstruct the correct density profile.
