Abstract
Imaging, rather than focusing, in systems of finite Fresnel number is considered. Incoherent systems, coherent systems, and scanning systems are discussed. Scanning systems exhibit spatially invariant imaging, while for conventional systems, coherent imaging is necessarily space variant. The optical transfer functions for incoherent systems are presented. Focusing with a circular pupil is compared with Gaussian beam propagation.
