Aperture

Nonparaxial effects on optical imaging are considered. It is shown that the dominant effect is on the axial variation in the complex amplitude, affecting most strongly depth of focus, interference microscopy, and the imaging of objects with appreciable depth. A so-called pseudoparaxial approximation is introduced, which gives reasonable prediction of these effects up to quite large angular apertures.
