T1 DIFFRACTION OF COHERENT RADIATION BY SURFACES HAVING NON‐GAUSSIAN STATISTICS OF ROUGHNESS JF Telecommunications and Radio Engineering JO TRE YR 2013 FD 2013-08-15 VO 72 IS 14 SP 1339 OP 1348 K1 speckle‐field K1 coherent radiation K1 statistical optics AB The character of scattering surface is determined by distribution of diffraction maximums obtained by interaction of diffraction field and a reflecting plane. However, the question of forming of the speckle fields observed as a result of interaction of coherent radiation with the diffusely scattering surfaces described by non‐Gaussian distribution of roughness is studied insufficiently. In this paper distribution of amplitude of the speckle fields appearing as a result of diffraction of laser radiation on the mechanically finished surfaces is investigated experimentally and theoretically. Mathematical simulation of the speckle fields the amplitude distribution of which are not subject to the Gaussian statistics has been carried out. It is proven that speckle‐fields formed as a result of interaction between coherent radiation and rough surfaces are not absolutely random and contain information about the degree of organization that characterizes the object.
