An Analysis of Aliasing for Sampling on Composite Lattices,
Abstract
In a previous paper, a quantitative analysis was given for the aliasing present in image transmission systems which sample the input with a two-dimensional periodic detector array. The present paper gives a quantitative analysis of the aliasing in similar systems, which produce a single picture by the superposition of several periodic samplings using a single detector array. The introduction of structure factor permits one to compute the precise reduction in amplitude of the aliased components that accompany the faithful image of each input spatial frequency. (Author)
