Abstract
Sampling is an inherent feature of all electronic imaging systems. The scene is spatially sampled in both directions due to the discrete locations of the detector elements. This sampling creates ambiguity in target edges and produces moiré patterns when viewing periodic targets. Aliasing becomes obvious when image features approach the detector size. Spatial aliasing is rarely seen in photographs or motion pictures because the grains are randomly dispersed in the photographic emulsion.
