Abstract
Peculiarities of the spatial behavior of the amplitude zero lines resulting from scattering of coherent radiation at random and fractal rough surfaces are studied. The optical correlation technique is proposed for diagnostics of phase singularities at a complex speckle field by comparison of the correlation lengths of amplitude and intensity of the local fields. It is shown that the dislocation lines at the field scattered by fractal surface have fractal properties, while the dislocation lines scattered by random surface have no fractal properties.
