Paper Abstract

Researches of coherent properties of the vortex Bessel optical beams propagating in a uniform medium after reflection from a rough surface are developed. It is shown, that at low levels of a random roughness of a reflecting surface, the degree of coherence of a vortex Bessel optical beam essentially depends on value of a topological charge of an optical beam. In the central part of a two-dimensional field of degree of coherence the ring dislocation is formed, the number of rings in which is equal to value of a topological charge of a vortex optical beam. At high levels of a random roughness of a reflecting surface, mutual coherence function of a vortex Bessel optical beam coincides with the similar characteristic of an incoherent source.
