Problems of the phase object visualization for various spatial frequency filtration techniques and phase modulation depths are considered. The imaging by the distorter presented in the paper is sufficient to formulate conclusions concerning the visualization problems of the phase objects. Using the vectorial interpretation of the phase object imaging we have shown that the satisfactory choice of the visualization method depends on the phase modulation depth, therefore, for an unknown phase object it is necessary to dispose a few different methods simultaneously.
