Paper Abstract

Both coherence and polarization play an important role in microscopy. It was long ago established that, in the context of scalar treatments, Köhler and critical illumination produce equivalent coherence functions in an object plane. This paper examines this equivalence in the context of polarization vortex illumination. Using a reversed-wavefront Young interferometer (RWYI), we show measurements of the coherence and correlation properties of the output illumination plane of various illumination systems. We compare the coherence properties of critical and Köhler vortex illumination schemes and look at the effects these properties have in an imaging system.
