This paper discusses the imaging properties of synthesized and digital holograms. Special attention is paid to how their structural discreteness affects the image reconstruction. The conditions for spatial separation of the diffraction orders of the hologram are formulated. Recommendations are given and substantiated for choosing the angle of incidence of the reference wave during the recording or synthesis of the hologram so that this angle is optimal from the viewpoint of the attainable width of the spatial-frequency spectrum of the reconstructed image.
