An approximate method is presented for calculating the distribution of refractive index in an axisymmetric inhomogeneity formed in a wind tunnel or ballistic facility. Calculations are performed on the basis of interferometer measurements in a divergent beam. The mathematical model of the inhomogeneity is considered.
