TLDR
An expression for the distribution of light in the image of two small apertures which are illuminated by a condenser of numerical aperture equal to s times that of the imaging objective is given in this paper.Abstract:
An expression is found for the distribution of light in the image of two small apertures which are illuminated by a condenser of numerical aperture equal to s times that of the imaging objective The resolving power of the system is written ρ=Kλ/(NA), and K is found as a function of s It is shown that precisely the same result obtains for both critical and Kohler illuminationread more

Image formation of thick three-dimensional objects in differential-interference-contrast microscopy
TL;DR: The goal of this work is to model the image formation process of thick three-dimensional objects in DIC microscopy using a combined geometrical and physical optics approach and it captures the major DIC image characteristics of the simulated object.

The concept of degree of coherence and its application to optical problems
TL;DR: In this article, the maximum visibility of the interferences obtainable from two points in a wave field is defined as their degree of coherence γ, which depends only on the aperture of the illuminating cone.

The theory of the microscope
TL;DR: In this paper, the diffraction effects produced by two adjacent apertures and a series of aperture in an opaque screen situated in the focal plane of a lens system are examined.
