Optimum sampling parameters for generalized holographic stereograms
Pierre St-Hilaire · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1997
It is well known that unproper sampling of discrete perspective images can result in readily visible artifacts. Previous work has used partial coherence theory to calculate the characteristics of sampled perspective imaging in the case where the viewer's pupil coincides with the perspective window. I now apply the same formalism to treat the general case where the viewer position is independent of the perspective window. This allows the theory to be used in the treatment of generalized holographic stereograms (ultragrams) and other unconventional geometries.
