Abstract
The use of Gaussian probing beams for measuring parameters of distributed lenses is well known. But common methods become invalid in widespread cases when investigated media contain additive scattering inhomogeneities. This report is devoted to the usual scheme generalization able to overcome mentioned restrictions. It is shown that utilizing arbitrary paraxial probing beams, characterized by space-angle intensity moments, enables us to solve this task effectively. The equations for evolution of moments in lens-like media with small- scale stochastic inhomogeneity are derived and analyzed, on which basis some recommendations are made for fast and suitable measurement of medium parameters.
