Investigation of Phase Singularities in the Vicinity of Small Structures Using a Linnik Interference Microscope

We present studies of the electric field that is reflected by sub-λ-structures. The occurence of singularities in the phase distribution of the field is investigated theoretically and experimentally with regard to the possibility to achieve lateral superresolution. A theoretical model for the calculation of the electric field is discussed that is based on the Green function formalism. Measurements on two-dimensional objects were performed using a Linnik interference microscope.
