TLDR
In this paper, Fraunhofer diffraction patterns produced by a circular aperture suffering from spherical aberration and illuminated by partially coherent light are presented, and tolerances for the value of the coefficient of aberration based on the Strehl criterion have been calculated for various values of correlation intervals contained in the aperture.Abstract:
Fraunhofer diffraction patterns produced by a circular aperture suffering from spherical aberration and illuminated by partially coherent light are presented. Improvement in the images has also been shown when an appropriate amplitude filter is used. Tolerances for the value of the coefficient of aberration based on the Strehl criterion have been calculated for various values of correlation intervals contained in the aperture. Two forms of mutual coherence function and four values of aberration coefficient have been assumed.read more

Applications of coherence theory in microscopy and interferometry
TL;DR: In this article, a general treatment of the influence of the size of the source on the visibility of the fringes in two-beam interferometers is given, together with some of the more immediate applications.

The Resolving Power of a Coated Objective
TL;DR: In this article, a method for reducing the diameter of the central bright disk in the diffraction pattern produced by an objective from an unresolved pinhole as object is described, where the coefficients of this series automatically determine both the characteristics of diffraction patterns and of the corresponding coating which must be applied to the exit pupil.

Application of the Sampling Theorem to Optical Diffraction Theory
TL;DR: In this article, the sampling theorem is applied to optical diffraction theory as a computational tool and formulas are developed in terms of sampled values of the point spread function for the transfer function, total illuminance, line spread function and cumulative line spread functions.

On the Propagation of Mutual Coherence
TL;DR: In this paper, it was shown that the mutual coherence function in a quasi-monochromatic field can be expressed as the product of a wave function with its complex conjugate, each factor depending on the coordinates of one point only.

Diffraction by Apertures Illuminated with Partially Coherent Light
TL;DR: In this paper, the Fraunhofer diffraction patterns of slit and circular apertures illuminated with partially coherent light were examined both theoretically and experimentally, and it was shown that a detailed knowledge of the mutual coherence function across the diffracting aperture is required to describe fully the diffraction phenomena.
