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 stable and spiral beams [PDF]
Journal of the Optical Society of America A, 2013 Stable and spiral coherent beams, which do not change the form of their intensity distribution apart from possible scaling and rotation during propagation and therefore possess self-healing properties, are widely applied in science and technology. On the other hand, it has been found that partially coherent light often provides better output than ...

Coupling Efficiency of a Partially Coherent Radially Polarized Vortex Beam into a Single-Mode Fiber
Applied Sciences, 2018 We study the problem of coupling partially coherent radially polarized (PCRP) vortex beams into a single-mode optical fiber. Using the well-known concept of the cross-spectral density (CSD) matrix, we derive a general expression for the coupling ...

Holographic beam shaping of partially coherent light
Optics Letters, 2022 We present an algorithmic approach for holographic shaping of partially coherent light, which is described by a mode expansion containing thousands of individual modes. Using gradient descent and algorithmic differentiation, our algorithm is able to find a set of axially separated phase patterns such that each mode undergoes an individually optimized ...

Results in PhysicsThe spectral degree of coherence (SDOC) evolution of partially coherent vortex beam with radially and azimuthally polarized (RPV and APV) beams in atmospheric turbulence have been studied and the results indicate that SDOC distribution will gradually ...

Beam Properties of a Partially Coherent Beam Propagating Horizontally in Atmospheric Turbulence
Photonics, 2023 This study explored the impact of atmospheric turbulence on partially coherent light propagation. Atmospheric turbulence causes random modulation of the intensity and phase of light, resulting in a speckle pattern in the far field.

Generation and Propagation of Partially Coherent Power-Exponent-Phase Vortex Beam
Frontiers in Physics, 2021 We report on a partially coherent power-exponent-phase vortex beam (PC-PEPV), whose spatial coherence is controllable and the initial phase exhibits a periodic power exponential change.

Partially Coherent Off-Axis Double Vortex Beam and Its Properties in Oceanic Turbulence
Photonics, 2023 A partially coherent off-axis double vortex beam (PCOADVB) composed of two off-axis vortices is theoretically presented. The analytical equations of a PCOADVB in oceanic turbulence are presented, and the intensity profiles and the number of coherence ...
