Abstract: Unlike holograms of real objects, holographic stereograms consist of information recorded from a relatively small number of discrete viewpoints. As discrete imaging systems, holographic stereograms are susceptible to aliasing artifacts caused by insufficient or improper sampling. A characterization of sampling-related image artifacts in holographic stereograms is presented. Constraints on image extent and resolution imposed by sampling are outlined. Methods of reducing or eliminating aliasing artifacts in both photographically-recorded and computer-generated holographic stereogram images are described. Results of this analysis can be generalized to describe other autostereoscopic displays.!8
