TLDR
In this article, the effects of condenser transmission characteristics upon the performance of partially coherent systems have been investigated, and the effect of the condenser size and transmission upon the two-point resolution of the system has also been examined.Abstract:
The effects of condenser transmission characteristics upon the performance of partially coherent systems have been investigated. It has been shown that the transmittance of the condenser aperture affects the coherence conditions prevailing upon the object plane and modifies the image forming properties of the system. Two different types of irradiance distribution functions have been assumed, in the first type the irradiance is maximum at the centre and tapers off towards the edges of the aperture, the reverse being true for the second type. Their influence upon the spatial frequency response and the edge response of the system has been investigated. The effect of the condenser size and transmission upon the two-point resolution of the system has also been examined.read more

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.

The Concept of Partial Coherence in Optics
TL;DR: In this paper, it was shown that the diameter of the area of coherence on a plane illuminated by a source of angular radius is given by d = d = 0 √ √ n √ 16 λ n N ε, where N is the refractive index of the intervening medium.
