Published in 2019 at "Ultramicroscopy"

DOI: 10.1016/j.ultramic.2019.01.015

Abstract: We present the extended Fourier Optics (FO) approach for modeling image formation in aberration-corrected low energy electron microscopy (ac-LEEM). The FO formalism is also generalized for image simulations of one or two-dimensional objects in ac… read more here.

Published in 2020 at "Ultramicroscopy"

DOI: 10.1016/j.ultramic.2020.113024

Abstract: Abbe theory of image formation can be expanded from two-dimensional to three-dimensional space. It has to consider an optical system that forms an image of a grating in an object space. It is possible to… read more here.

Published in 2020 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stab577

Abstract: In a recent paper, we have discussed the higher order singularities in gravitational lensing. We have shown that a singularity map, comprising A3- lines and unstable (point) singularities (A4 and D4), is a compact representation… read more here.

Published in 2018 at "IEEE Transactions on Geoscience and Remote Sensing"

DOI: 10.1109/tgrs.2017.2763147

Abstract: For a single-channel synthetic aperture radar (SAR), finite-pulse repetition frequency and nonideal antenna pattern cause azimuth ambiguities, i.e., ghosts in image domain. In this paper, a novel algorithm of locating processing weighted group lasso SAR… read more here.

Published in 2025 at "IEEE Transactions on Industrial Informatics"

DOI: 10.1109/tii.2025.3584547

Abstract: Underwater imaging in turbid environments presents significant challenges for industrial applications due to optical distortions that severely degrade image quality. This article addresses the fundamental information deficit in traditional single-image restoration methods by introducing the… read more here.

Published in 2021 at "Biomedical Optics Express"

DOI: 10.1364/boe.420992

Abstract: Full-wave models of OCT image formation, which are based on Maxwell’s equations, are highly realistic. However, such models incur a high computational cost, particularly when modelling sample volumes consistent with those encountered in practice. Here,… read more here.

Published in 2020 at "Optics letters"

DOI: 10.1364/ol.404654

Abstract: We report on the investigation of spectral leakage's impact on the reconstruction of Fourier-domain optical coherence tomography (FD-OCT). We discuss the shift-variant nature introduced by the spectral leakage and develop a novel spatial-domain FD-OCT image… read more here.
