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.

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.

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.

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.

DOI: 10.1109/tgrs.2022.3167724
Abstract: Satellite remote sensing acquisitions are usually processed after downlink to a ground station. The satellite travel time to the ground station adds to the total latency, increasing the time until a user can obtain the… read more here.

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.
