Abstract
Theoretical aspects of off-axis holographic zone plate recording using two cylindrical waves, with arbitrary angled focal lines, and replay of such holograms with a cylindrical or spherical wave are discussed in the narrow-beam approximation. Expressions for the distances and orientations of focal lines of generally reconstructed astigmatic beams are given, and conditions for obtaining spherical waves are analysed. The results have been verified by experiments using photographic emulsion (Agfa-Gevaert Holotest 10E56 plates) as the recording material. In particular, experimentally obtained parameters of the reconstructed astigmatic beam and the spherical wave are found to be in good agreement with theoretical results.
