Аннотация:
An apodization scheme for increasing the Sparrow resolution limit under the partially coherent illumination is formulated via the calculus of variations. The required pupil functionsa re obtained by solving an homogeneous Fredholm integral equation and evaluated as functions of the coherence condition of illumination and the total light flux passing through the aperture.
