Gabor diffraction microscopy: The hologram as a generalized zone-plate

Abstract

SINCE the publication of the papers of Gabor on diffraction microscopy 1,2, work has been going on in this Laboratory on the effect of varying the source-hologram distance and the hologram size on the position of the reconstituted image. It proves possible to represent the information obtained in a very simple way by the use of an instructive analogy. © 1950 Nature Publishing Group.
