Abstract
The single-sideband technique eliminates a conjugate image and zeroth order diffraction light, producing only a reconstructed image of a hologram. A band-limited cosine zone plate appropriate for use with the single-sideband technique is derived. The width of the zone plate is half that of a conventional zone plate in one direction. The proper selection of a transmitted spatial frequency band leads to an interlaced band-limited zone plate that has complex amplitudes in odd or even rows. The use of such a zone plate reduces calculation time for a hologram to approximately 75%. Experimental verification of this is presented.
