Generalized Zernike or disc polynomials: An application in quantum optics

open access: yes, 2007
An application of the “generalized Zernike or disc polynomials”, recently introduced in the literature, is shown, resorting to the Lie algebra based investigation of the dynamics of quantum systems driven by two-mode interaction Hamiltonians.

Zernike Polynomials and Optical Aberration

open access: yes, 2016
The Zernike polynomials are commonly used in the analysis of adaptive optics systems. Annular Zernikes are particularly useful for analyzing the aberrations of telescopes with annular pupils (e.g., Cassegrain telescopes).

PSF Estimation of Space-Variant Ultra-Wide Field of View Imaging Systems

open access: yesApplied Sciences, 2017
Ultra-wide-field of view (UWFOV) imaging systems are affected by various aberrations, most of which are highly angle-dependent. A description of UWFOV imaging systems, such as microscopy optics, security camera systems and other special space-variant ...

A new operational matrix method to solve nonlinear fractional differential equations

open access: yesNonlinear Engineering
This study aims to propose novel Zernike wavelets and a new method based on the operational matrices for solving nonlinear fractional differential equations. First, non-orthogonal Zernike wavelets are introduced using the Zernike polynomials. Then, a new

Orthogonality and convergence of discrete Zernike polynomials

open access: yes, 2011
The Zernike polynomials are an infinite set of orthogonal polynomials over the unit disk, which are rotationally invariant. They are frequently utilized in optics, opthal- mology, and image recognition, among many other applications, to describe ...
