Paper Abstract

In this paper we consider super-resolution by digital holography. We start from an early experiment by Wolter (1964); from its analysis we derive some examples where we obtain parameters of dipole arrays from measurements in the far field. We show (by relevant example) that it is possible to represent (reflecting) objects by arrays of dipoles. The measurement of complex field amplitudes in the far field is limited by noise. When we use the Gerchberg algorithm to reconstruct the field in the object plane, most of this noise is filtered away. This leads to an increase SNR of the total reconstruction process; we can hope for a resolution of the order of λ/10. We propose an optical set-up with which an experimental confirmation can be realized.
