TLDR
In this paper, a far field intensity distribution has been plotted for a circular aperture suffering from spherical aberration and illuminated by quasi-monochromatic partially space-coherent light.Abstract:
Far-field intensity distribution has been plotted for a circular aperture suffering from spherical aberration and illuminated by quasi-monochromatic partially space-coherent light. Gaussian and besinc forms of correlation have been assumed. It is shown that higher values of coefficient of aberration can be tolerated as the value of number of correlation intervals contained in the aperture increases.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.

The detection and resolution of incoherent objects by an aberrated optical system in the presence of background noise
TL;DR: The detection and resolution of an object, and an estimation of its parameters, such as position and radius, have been treated by signal detection theory as mentioned in this paper, and it was observed that the detectability, resolution, and accuracy in the determination of the parameters decreased with an increase in the aberration coefficient, though the decreases were smaller for partially coherent light than for coherent light.

Properties of a Defocused Optical System
TL;DR: In this article, the exact diffraction optical transfer function (OTF) and point spread function (PSF) are compared to the geometrical OTF and PSF, respectively, for both small and large amounts of defocusing.

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.
