Recursive computation of generalised Zernike polynomials
(Elsevier B.V., 2017-03-01)
An algorithmic approach for generating generalised Zernike polynomials by differential operators and connection matrices is proposed. This is done by introducing a new order of generalised Zernike polynomials such that it ...
Accuracy of Zernike polynomials in characterizing optical aberrations and the corneal surface of the eye
(Assoc Research Vision Ophthalmology Inc, 2005-06-01)
PURPOSE. Zernike polynomials have been successfully used for approximately 70 years in many different fields of optics. Nevertheless, there are some recent discussions regarding the precision and accuracy of these polynomials ...
Generalized convolution roots of positive definite kernels on complex spheres
(National Academy of Sciences of Ukraine, Institute of MathematicsKyiv, 2015)
Convolution is an important tool in the construction of positive definite kernels on a manifold. This contribution provides conditions on an 'L POT.2'-positive definite and zonal kernel on the unit sphere of 'C POT.Q' in ...

Corneal aberrations in keratoconic eyes: influence of pupil size and centering
(IOP Publishing, 2011-02)
Ocular aberrations vary among subjects and under different conditions and are commonly analyzed expanding the wavefront aberration function in Zernike polynomials. In previous articles, explicit analytical formulas to ...
Desempenho óptico de lentes intraoculares: nfluência das alterações de posicionamento e do poder dióptrico.
(Universidade Federal de Minas GeraisUFMG, 2017-03-13)
Purpose: To analyze the magnitude of low and high order aberrations of different commercially available intraocular lenses (IOLs). To analyze the importance of these aberrations in the IOLs optical performance when they ...
Frentes de ondas (wavefronts) e limites da visão humana Parte 1: fundamentos
(Conselho Brasileiro de Oftalmologia, 2002-12-01)
Light spreads out uniformly at the same speed in all directions. Its position at any given moment is a sphere that connects all the corresponding phase points, having the source at its center. Such imaginary spherical ...
