Abstract
In this paper, it is pointed out that the sampled imaging systems are not spatially invariant in single sampling area unit, but they are spatially invariant in large field on the basis of integral sampling theory in optics. The concept and the measurement method of equivalent modulation transfer function (MTFe) are first given. The experiment results prove that this evaluation method can overall and correctly show the imaging quality of sampled imaging systems, and the MTFe can be measured conveniently.
