Fundamental diffraction limitations in a paraxial 4-f imaging system with coherent and incoherent illumination.


In the usual model of an imaging system, only the effects of the aperture stop are considered in determining diffraction-limited system performance. In fact, diffraction at other stops--those associated with different lens elements, for example--can also affect system performance and cause the imaging to be space variant, even in the absence of vignetting… (More)
