TLDR
In this article, an optimal balance of spherical aberrations under partially coherent illumination is presented, where the visibility of a two-point image as a merit function is used to estimate the image aberration.Abstract:
An optimal balance of spherical aberrations under partially coherent illumination is presented. The visibility of a two-point image as a merit function is used to estimate the image aberrations. Although the optimal balance of aberrations has been evaluated by Marechal [ Rev. Opt.2, 257 ( 1947)] and Wang [ Proc. Phys. Soc. London53, 157 ( 1941)] for incoherent illumination, it has not been treated for partially coherent illumination. In this paper, a general relationship between the optimal balance of aberrations and the degree of mutual coherence under partially coherent illumination is discussed. The result obtained for incoherent illumination turns out to be a special case of that for partially coherent illumination. In other words, the result of optimal balance of aberrations under partially coherent illumination is a general case that includes coherent, incoherent, and partially coherent illumination.read more

On the diffraction theory of optical images
TL;DR: The theory of image formation is formulated in terms of the coherence function in the object plane, the diffraction distribution function of the image-forming system and a function describing the structure of the object.

The concept of partial coherence in optics
TL;DR: In this article, it was shown that the diameter of the area of coherence on a plane illuminated by a source of angular radius α is given by d = 0.16λ/N sin α, where N is the refractive index of the intervening medium.

Aberration-variance-based formula for calculating point-spread functions: rotationally symmetric aberrations
TL;DR: By using exponential evaluations of the Strehl ratio and appropriate Dini-sampling formulas in concert, an approximate formula is derived for fast calculation of intensity distributions in the central bright core of rotationally symmetric aberrational diffraction patterns.
