Uncertainty principle for partially coherent light

Journal of the Optical Society of America, 1983
Two intensity functions are introduced for partially coherent light: one in a space domain and a second one in a spatial-frequency domain. Moreover, a quantity is defined that can be considered a measure of the overall degree of coherence of the partially coherent light.

Linear axicons in partially coherent light

Optical Engineering, 1995
With uniform partially coherent illumination of a sufficiently small coherence width, linear holographic axicons produce an extended axial line image of a desired length and a nearly uniform intensity. This result is demonstrated by numerical diffractive simulations based on generalized axicon phase functions and the space-frequency theory of optical ...

Coherence vortices in Mie scattered partially coherent light

2017
Although the fields of coherence optics and Mie scattering have been separately subjected to extensive investigations for some time, no work has been carried out combining these two hitherto distinct concepts. In particular, despite the fact that many scientists have performed numerous studies on optical singularities in various systems, no work is ...

Phase imaging with partially coherent light

SPIE Proceedings, 2013
We review several quantitative phase imaging methods that retrieve phase from a through-focus series of intensity images (specifically, iterative methods and Transport of Intensity) and compare their performance when using partially coherent illumination, such as in the case in a brightfield microscope or X-ray imaging system.

Propagation of Partially Coherent Light Pulses

Optica Acta: International Journal of Optics, 1986
The propagation of light pulses with partial spatial and temporal coherence is analysed. It is shown that the introduction of the second-order coherence function enables the description of both spatial and temporal radiation characteristics to be described in the angular spectrum approach.
