Modeling of the high-resolution optical-coherence diagnostics of bi-refringent biological tissues
Frontiers in Physics, 2023 We present a computer model of the polarization-sensitive interference diagnostics of the bi-refringent biological media, with a particular example of the lamella of eye cornea.

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.

Wigner transform approach to dynamic-variable partially coherent laser beam characterization [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 1) Background: the modeling, characterization, transformation and propagation of high-power CW laser beams in optical (including fiberoptic) trains and in the atmosphere have become hot topics in laser science and engineering in the past few years ...

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
