Abstract

This paper deals with quantification of a two-dimensional (2- D) sampling process by pixel array. The idea is based on transformation of the Wigner-Seitz cell, which defines the sampling lattice in the spatial domain, into a 'bandwidth cell' in the spatial frequency domain. The area of the bandwidth cell is a quantitative measure of the sampling process. On this basis a description of the oversampling process is developed. We compare different configurations of the sampling pixel array. ©2004 Copyright SPIE - The International Society for Optical Engineering.
