Paper Abstract

Using a zone plate interferometer we have demonstrated image-plane holographic microscopy employing the radiation of a compact capillary discharge Ar laser operating at 46.9 nm for illumination. In this paper we describe a full analysis of the spatial resolution of the system and demands on the coherence of the radiation. The analysis shows that the resolution in the amplitude and phase images is mainly determined by the numerical aperture of the imaging element and the wavelength of the illumination. The resolution, however, is not affected by the degree of coherence, which only reduces the field of view. We also show rather low demands on temporal coherence due to the common-path interferometric geometry.
