Optical testing by using the chromatic split of non-classical localization planes
When a spatially incoherent, periodic, quasi-monochromatic source illuminates a two-beam amplitude division interferometer verifying the equivalent sine condition, successive non-classical localization planes appear.

| Sumario: | When a spatially incoherent, periodic, quasi-monochromatic source illuminates a two-beam amplitude division interferometer verifying the equivalent sine condition, successive non-classical localization planes appear. If the radiation is polychromatic, then each plane splits and the plane corresponding to a given wavelength can be viewed distinctly by interposing an adequate filter. Thus, by interchanging filters and with no other change in the configuration, a non-classical localization plane is shifted. 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. |
