When a spatially incoherent, periodic, quasi-monochromatic source illuminates an amplitude division two beam interferometer verifying the equivalent sine condition, successive non-classical localization planes appear. If the radiation is polichromatic each plane splits and that corresponding to a given wavelength can be distinctly viewed interposing an adequate filter. Thus interchanging filters and with no other change in the configuration, a non-classical localization plane shifts. In the present paper this shift is employed to examine various transversal planes of a thick transparent specimen with a few phase disturbances distributed in its volume. Results obtained with a Wollaston prism are shown.
