Enhancement of Partially Coherent Diffractive Images Using Generative Adversarial Network
AI, 2022 We present a deep learning-based generative model for the enhancement of partially coherent diffractive images. In lensless coherent diffractive imaging, a highly coherent X-ray illumination is required to image an object at high resolution.

Partially coherent sources with circular coherence [PDF]
Optics Letters, 2017 A new class of partially coherent light sources is introduced. At the source plane, they exhibit perfect coherence along any annulus that is concentric to the source center. Between two points at different distances from the center, coherence can be partial or even vanishing.

Spatial spectrum of coherence signal for a defocused object images in digital holographic microscopy with partially spatially coherent illumination [PDF]
Компьютерная оптика, 2018 We study the effect of a decrease in the magnitude of the coherence signal in high-frequency spatial spectrum for a defocused object image in transmission digital holographic microscopy with quasimonochromatic partially spatially coherent illumination. A

Partial Recovery of Coherence Loss in Coherence-Assisted Transformation
Entropy, 2023 Coherence-assisted transformation under incoherent operations is discussed. For transformation from the pure state to the mixed state, we show that the coherence loss can be partially recovered by adding auxiliary coherent states.

Coherent-mode decomposition of partially polarized, partially coherent sources [PDF]
Journal of the Optical Society of America A, 2003 It is shown that any partially polarized, partially coherent source can be expressed in terms of a suitable superposition of transverse coherent modes with orthogonal polarization states. Such modes are determined through the solution of a system of two coupled integral equations. An example, for which the modal decomposition is obtained in closed form

Computation of Hopkins’ 3-circle integrals using Zernike expansions [PDF]
Journal of the European Optical Society-Rapid Publications, 2011 The integrals occurring in optical diffraction theory under conditions of partial coherence have the form of an incomplete autocorrelation integral of the pupil function of the optical system.

Partially coherent ultrafast spectrography [PDF]
Nature Communications, 2015 AbstractModern ultrafast metrology relies on the postulate that the pulse to be measured is fully coherent, that is, that it can be completely described by its spectrum and spectral phase. However, synthesizing fully coherent pulses is not always possible in practice, especially in the domain of emerging ultrashort X-ray sources where temporal ...
