Aberrations and accommodation [PDF]
Clinical and Experimental Optometry, 2020 Modern methods of measuring the refractive state of the eye include wavefront sensors which make it possible to monitor both static and dynamic changes of the ocular wavefront while the eye observes a target positioned at different distances away from the eye.

Aberration-corrected transmission electron microscopy with Zernike phase plates
, 2022 We explore the possibility of applying physical phase plates (PPs) in combination with aberration-corrected transmission electron microscopy. Phase-contrast transfer characteristics are calculated and compared for a thin-film based Zernike PP, a hole ...

Spatial rainbows and catastrophes in transmission of protons through electrostatic octopole lens [PDF]
Nuclear Technology and Radiation Protection, 2018 This paper considers transmission of initial parallel proton beam with kinetic energy of 10 kеV through electrostatic octopole lens. The spatial rainbows and corresponding proton distributions are calculated by using infinite length ...

Automatic Modal Wavefront Estimation and Correction for Optical Aberration
IEEE Photonics Journal, 2019 Modal estimation of aberration can quantify the amount of aberration, which plays an important role in optical system optimization, aberration correction, and so on. Here, we propose a simple but effective method to find the modal wavefront of aberration.

Analysis of Aberration Effects on Flow Imaging and Quantification in Echocardiography
IEEE Open Journal of Ultrasonics, Ferroelectrics, and Frequency Control, 2023 In medical ultrasound, aberration is a phenomenon that causes distortion of the ultrasound wavefront as it travels through an inhomogeneous medium. Aberration has been investigated since the 1960s and is known as a major cause of image quality loss in ...

Aberration-Aware Depth-From-Focus
, 2023 Computer vision methods for depth estimation usually use simple camera models with idealized optics. For modern machine learning approaches, this creates an issue when attempting to train deep networks with simulated data, especially for focus-sensitive ...
