CGH based on partially coherent light
AOPC 2019: Display Technology and Optical Storage, 2019A new expression of partially coherent light is derived. The formula of the partially coherent optical field is consisted of two terms: spatially coherent part propagated by angular spectrum and incoherent part based on the optical transfer function. Both parts are related to coherent function (degree of coherence).

A scattering experiment with partially coherent light
Optics Communications, 1990A scattering experiment is described in which the spatial coherence properties of the incident light can be changed. The effect of spatial coherence on the angular distribution of the scattered radiation is studied. The results agree with the predictions of a recent analysis of this phenomenon [J. Jannson, T. Jannson and E.

Radiance Theorem with Partially Coherent Light
Optica Acta: International Journal of Optics, 1986The transmission of a generalized radiance across a planar boundary separating two homogeneous media is considered. It is assumed that the optical field remains continuous at the interface and reflection is neglected. A result is obtained which may be regarded as a generalization of the conventional radiance theorem for fields of any state of coherence.

Fourier Transformation in Partially Coherent Light
Optica Acta: International Journal of Optics, 1975Fourier transformation in partially coherent light has been theoretically studied. It is shown that the intensity distribution at the back focal plane of a lens when a transparency located at the front focal plane and illuminated by a partially space coherent light is given by the convolution of the Fourier transform of mutual intensity function and ...

Linear axicons in partially coherent light
Optical Engineering, 1995With 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
2017Although 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 ...

Encoding skyrmions in the partial coherence of light
CLEO 2026We demonstrate that optical skyrmions can be encoded in one-dimensional partially-coherent light via low-rank coherency matrices. These coherence skyrmions exhibit robustness to noise and could be generated and measured using partially coherent light analyzers.

Phase imaging with partially coherent light
SPIE Proceedings, 2013We 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, 1986The 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.
