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.
