摘要：

A method for measuring the angular size of the halo from boundary diffraction waves without using two-position schemes is proposed. The relationship between the angular distortions of the beam and the size distribution of inhomogeneities is derived for a random transmitting screen. The effective size of inhomogeneities is expressed in terms of the ratio between the fourth-order and second-order moments of the distribution function. A method for estimating the correspondence between the effective size of the inhomogeneities and the parameters of the real screen is substantiated. The key relation for the estimation is the equality of the angular sizes of the halo for the simulated and real scattering objects.
