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. 1. INTRODUCTION Holographic stereography is the most widely used holographic technique for producing three-dimensional imagery from two-dimensional views. Holographic stereograms are the result of the merger of two approaches to three-dimensional imagery: display holography, with its roots in the wor...
