摘要：
Peculiarities of the spatial behavior of the amplitude zero resulting from scattering of coherent radiation at random rough surfaces are studied. The optical correlation technique is proposed for diagnostics of phase singularities at a complex speckle field. It is shown that the coordinate distribution of the phase singularities at the field with coaxially imposed reference wave provides visualization of strongly scattering objects.
