Cyclostationarity: New trends and applications

A Napolitano - Signal processing, 2016 - Elsevier
A concise survey of the literature on cyclostationarity of the last 10 years is presented and an
extensive bibliography included. The problems of statistical function estimation, signal …

Nonstationary optics: tutorial

M Koivurova, J Laatikainen, AT Friberg - JOSA A, 2024 - opg.optica.org

for a multitude of novel applications. These include areas of research such as …

Wolf effect of partially coherent light fields in two-dimensional curved space

C Xu, A Abbas, LG Wang, SY Zhu, MS Zubairy - Physical Review A, 2018 - APS
Wolf effect refers to a spectral shift of light during its propagation even in free space, which
results from the fluctuating (or correlation) nature of light sources. In conventional optics, the …

Complex Gaussian representation of statistical pulses

SA Ponomarenko - Optics express, 2011 - opg.optica.org
We develop a general representation for ensembles of non-stationary random pulses in
terms of statistically uncorrelated, time-delayed, frequency-shifted Gaussian pulses which …

Coherence vortices in Mie scattering of statistically stationary partially coherent fields

ML Marasinghe, M Premaratne, DM Paganin - Optics Express, 2010 - opg.optica.org
Points within a fully coherent complex scalar optical field, where the amplitude is identically
zero but the optical phase has a jump discontinuity, have been widely investigated by the …

Speckled cross-spectral densities and their associated correlation singularities for a modern source of partially coherent x rays

DM Paganin, MS del Río - Physical Review A, 2019 - APS
We consider a realistic model for calculating the cross-spectral density of partially coherent
beams from an x-ray undulator in a modern storage ring. This two-point coherence function …

Ultrashort pulse coherence properties in coherent linear amplifiers

L Mokhtarpour, SA Ponomarenko - JOSA A, 2013 - opg.optica.org
We examine coherence properties of small-area, intrinsically stationary statistical pulses
propagating in amplifying media in the vicinity of an optical resonance. Any such medium …

Web service composition technique based on a service graph and particle swarm optimization

VR Chifu, CB Pop, I Salomie… - Proceedings of the …, 2010 - ieeexplore.ieee.org

General interference law for nonstationary, separable optical fields

V Manea - JOSA A, 2009 - opg.optica.org
An approach to the theory of partial coherence for nonstationary optical fields is presented.
Starting with a spectral representation, a favorable decomposition of the optical signals is …

Propagation of spatial coherence in fast pulses

RW Schoonover, BJ Davis, RA Bartels, PS Carney - JOSA A, 2009 - opg.optica.org
Diffraction and interferometry with fast pulses are analyzed for the case that the fields are
partially correlated in time and in space. This generalizes a previous work [Schoonover, J …
