Effects of Atmospheric Turbulence on Lensless Ghost Imaging with Partially Coherent Light [PDF]

open access: goldApplied Sciences, 2018
Ghost imaging with partially coherent light through two kinds of atmospheric turbulences: monostatic turbulence and bistatic turbulence, is studied, both theoretically and experimentally.

Coherence vortices in Mie scattered partially coherent light

open access: green, 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 ...

Paraxial Propagation of Scattered Light Based on the Chirp Z-Transform [PDF]

open access: yesSensors
In the simulation of partially coherent light propagation within optical systems utilizing the Wigner function, the constraints imposed by the Fourier transform necessitate that the dimensions of the input and output matrices remain congruent ...

Imaging with partially coherent light: elementary-field approach

open access: goldOptics Express, 2015
Numerical modeling of bright-field and dark-field imaging with spatially partially coherent light is considered. The illuminating field is expressed as a superposition of transversely shifted fully coherent elementary fields of identical form. Examples of imaging under variable coherence conditions demonstrate the computational feasibility of the model

Focusing of partially coherent light into planar waveguides

open access: goldOptics Express, 2004
Edge coupling of a focused partially coherent Gaussian Schell-model beam into a planar dielectric waveguide is examined. The incident field is decomposed into a sum of coherent modes that are expressed as a discrete superposition of plane-wave components. A model based on the rigorous diffraction theory of gratings is used to replace the waveguide with
