In this paper we examine the effects of random-phase spatial sampling on the optical character recognition process. We start by presenting a detailed analysis in the case of 1-dimensional patterns. Empirical data demonstrate that our model is accurate. We then give experimental results for more complex, 2-dimensional patterns (i.e. printed, scanned characters). Spatial sampling seems to account for a significant amount of the variability seen in practice.
