Scattering of partially coherent surface plasmon polariton fields by metallic nanostripe

open access: yesJournal of the European Optical Society-Rapid Publications, 2019
Background Surface plasmon polaritons (SPPs) are electromagnetic waves that propagate at a metal-dielectric interface. Until recently, monochromatic, fully coherent SPPs have mainly been considered.

Partially coherent imaging and spatial coherence wavelets [PDF]

open access: yesOptics Communications, 2004
A description of spatially partially coherent imaging based on the propagation of second-order spatial coherence wavelets and marginal power spectra (Wigner distribution functions) is presented. In this dynamics, the spatial coherence wavelets will be affected by the system through its elementary transfer function. The consistency of the model with the

Accurate Light Field Depth Estimation Using Multi-Orientation Partial Angular Coherence

open access: yesIEEE Access, 2019
Occlusion is a critical issue that affects the accuracy for light field depth estimation. In the presence of occlusions, the photo-consistency property is broken, making ambiguity near occlusion areas.
