On the absence of phase-recording or `twin-image' separation problems in `Gabor' (in-line) holography

Abstract

In contrast with a general belief which followed Gabor's wavefront-reconstruction imaging work in 1948, the original Gabor `in-line' hologram recording scheme is shown to produce perfectly separable `twin images', without any phase-recording problems, notably in high-resolution imaging and with diffused illumination.
