Abstract

The factors which affect resolution in diffraction microscopy are studied. The inequality <i>p</i>λ>4<i>nd</i>/<i>N</i> is a necessary condition for making good holograms, where <i>p</i> is the distance between source and film, <i>d</i> is the diameter of the source, and λ is its wavelength, <i>n</i> is the number of recorded central bands of the diffraction pattern, and <i>N</i> is the resolving power of the film. The minimum theoretical resolvable distance between two point objects is limited by <i>d</i> and <i>N</i> but not by the wavelengths used in the analysis and reconstruction. Possible applications to the focusing of x-rays by Gabor techniques and by a single Fresnel zone plate are considered.
