Optical Holography with Partially Coherent Radiation [PDF]

open access: yes, 1981
Holograms can be formed in light of little or no temporal coherence. The coherence requirements for Gabor in‐line holography are examined. It is shown that, with achromatic interferometers formed from diffraction gratings, the coherence requirements for ...

Tight Focusing of Partially Coherent Vortex Beams

open access: yesInternational Journal of Optics, 2012
Tight focusing of partially polarized vortex beams has been studied. Compact form of the coherence matrix has been derived for polarized vortex beams.

Discrete solitons and soliton-induced dislocations in partially-coherent photonic lattices

open access: yes, 2004
We investigate the interaction between a light beam and a two-dimensional photonic lattice that is photo-induced in a photorefractive crystal using partially coherent light.

Single-Cycle High-Intensity Electromagnetic Pulse Generation in the Interaction of a Plasma Wakefield with Nonlinear Coherent Structures [PDF]

open access: yes, 2005
The interaction of coherent nonlinear structures (such as sub-cycle solitons, electron vortices and wake Langmuir waves) with a strong wake wave in a collisionless plasma can be exploited in order to produce ultra-short electromagnetic pulses.

Research Progress on the Twisted Partially Coherent Beams

open access: yesNantong Daxue xuebao. Ziran kexue ban, 2020
Under the action of twist phase, partially coherent beams display their unique advantages in many applications fields, such as beam shaping, particle trapping, optical imaging, free-space communications, and so on.

On 3-manifolds that support partially hyperbolic diffeomorphisms

open access: yes, 2010
Let M be a closed 3-manifold that supports a partially hyperbolic diffeomorphism f. If $\pi_1(M)$ is nilpotent, the induced action of f on $H_1(M, R)$ is partially hyperbolic.

The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Second-Order Statistics of Self-Splitting Structured Beams in Oceanic Turbulence

open access: yesPhotonics, 2023
Free-space optical communication is restricted by random media-stimulated beam degradation. However, partially coherent structured beams modulated by the coherence structure can potentially mitigate this negative effect. By employing the extended Huygens–

Detection of partially coherent optical emission sources [PDF]

open access: yes, 2000
Detection of airborne optical emission sources in Infrared Search and Track (IRST) systems is usually carried out using the blackbody temperature or emissivity difference between the emission source and the background.
