Fourier–Zernike Series of Convolutions on Disks

open access: yesMathematics, 2018
This paper presents a systematic study of the analytic aspects of Fourier⁻Zernike series of convolutions of functions supported on disks. We then investigate different aspects of the presented theory in the cases of zero-padded functions.

Computation of Hopkins’ 3-circle integrals using Zernike expansions [PDF]

open access: yesJournal 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.

Large Depth-of-Field, Large Eyebox, and Wide Field-of-View Freeform-Holographic Augmented Reality Near-Eye Display. [PDF]

open access: yesAdv Sci (Weinh)
This study proposes an augmented reality (AR) near‐eye display system that simultaneously achieves a large depth‐of‐field (DOF) from 0.25 to 10 m, a wide 50° field‐of‐view (FOV), and a 10 mm × 10 mm viewing eyebox, while maintaining high display performance, good optical see‐through viewing capability, and a compact system form factor.

Macrophage Phenotype Detection Methodology on Textured Surfaces via Nuclear Morphology Using Machine Learning

open access: yesAdvanced Intelligent Discovery, EarlyView.
A novel machine learning approach classifies macrophage phenotypes with up to 98% accuracy using only nuclear morphology from DAPI‐stained images. Bypassing traditional surface markers, the method proves robust even on complex textured biomaterial surfaces. It offers a simpler, faster alternative for studying macrophage behavior in various experimental

Straightforward path to Zernike polynomials [PDF]

open access: yesJournal of Micro/Nanopatterning, Materials, and Metrology, 2021
Starting from Weierstrass’ approximation theorem, Zernike polynomials are obtained by a few straightforward steps involving only the recast of the aberration function as a double sum in the polar coordinates followed by the weighted orthogonalization of a power series. The origin of the name Fringe Zernike polynomials is also explained.

A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

open access: yesActa Ophthalmologica, Volume 104, Issue 2, Page e122-e138, March 2026.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

Balanced Binary Tree Schemes for Computing Zernike Radial Polynomials

open access: yesIEEE Access, 2023
Zernike radial polynomials (ZRP) play a significant role in application areas such as optics design, imaging systems, and image processing systems. Currently, there are two kinds of numerical schemes for computing the ZRP automatically with computer ...

Clusters morphology by Zernike polynomials

open access: yesIl Nuovo Cimento C, 2021
The study of the morphology of multiwavelength images of galaxy clusters is largely used to infer their dynamical state. We presented a novel approach of morphological analysis based on modelling clusters images with Zernike polynomi- als (ZPs). We used mock maps of the thermal component of the Sunyaev-Zel’dovich (tSZ) effect generated for synthetic ...
