Paley–Wiener partially coherent sources
Optics LettersStarting from the extension to complex arguments of the ordinary Fourier transform (FT) (due to Paley and Wiener) and from results concerning reproducing kernels in Hilbert spaces, we define a new, to the best of our knowledge, class of partially coherent planar sources presenting a structured degree of coherence.

Overview: In this chapter we study the effects of a spatially partially coherent beam. Several investigations of the properties of such beams have led to the conclusion that the use of a diffuser at the exit aperture of a coherent laser can produce reduced scintillations at the receiver under the proper conditions.

Except for a brief foray into incoherent imaging in Chapter 7, we have been considering coherent light. Coherence refers to the amount of correlation in the optical field at separate times or separate points within a beam of light. High coherence leads to stationary interference effects such as the "fringing" and "ringing" structures that appeared in ...

Coherent-mode representation of partially coherent imaging
Frontiers in Optics 2004/Laser Science XXII/Diffractive Optics and Micro-Optics/Optical Fabrication and Testing, 2004The process of image formation in optical system with partially coherent illumination is represented as a superposition of completely coherent modal images. Two modal representations of a partially coherent imaging system are given. The basic concepts are illustrated by en example of calculating the image intensity distribution.
