Digital in-line holography with a spatially partially coherent beam [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 We propose in this paper an analytical solution to the problem of scalar diffraction of a partially coherent beam by an opaque disk. This analytical solution is applied in digital in-line holography of particles. We demonstrate that the reconstruction by

Partially Coherent Flat-Topped Beam Generated by an Axicon
Applied Sciences, 2019 The intensity distribution of a partially coherent beam with a nonconventional correlation function, named the multi-Gaussian Schell-model (MGSM) beam, focused by an axicon was investigated in detail.

Partially Coherent, Radially Polarized Beam with Annular Apodization [PDF]
The Scientific World Journal, 2014 Based on the vectorial Debye theory, the tight focusing properties of partially coherent, radially polarized vortex beams are investigated in detail. In this paper, we propose to use an amplitude modulated filter in combination with a high NA lens to ...

Abnormally autofocusing vortex Swallowtail Gaussian vector beam with low spatial coherence
New Journal of Physics, 2023 The precondition for the application of light beams is the ability to devise light distribution with high precision. Controlling more dimensions for structured light fields is an effective method to improve the ability to devise light distribution.
