Analytical ray transfer matrix for the crystalline lens

Navarro, Rafael; Lockett-Ruiz, Verónica; López García, José Luis

(OSA Publishing, 2022) Artículo / Artikulua

We present the formulation of a paraxial ray transfer or ABCD matrix for onion-type GRIN lenses. In GRIN lenses, each iso-indicial surface (IIS) can be considered a refracting optical surface. If each IIS is a shell or ...

Generalization of Zernike polynomials for regular portions of circles and ellipses

Navarro, Rafael; López García, José Luis

; Díaz, José A.; Pérez Sinusía, Ester

(Optical Society of America, 2014) Artículo / Artikulua

Zernike polynomials are commonly used to represent the wavefront phase on circular optical apertures, since they form a complete and orthonormal basis on the unit circle. Here, we present a generalization of this Zernike ...

Orthogonal basis for the optical transfer function

Ferreira González, Chelo

; López García, José Luis

; Navarro, Rafael; Pérez Sinusía, Ester

(Optical Society of America, 2016) Artículo / Artikulua

We propose systems of orthogonal functions qn to represent optical transfer functions (OTF) characterized by including the diffraction-limited OTF as the first basis function q0 OTF perfect. To this end, we apply a powerful ...

Orthogonal basis with a conicoid first mode for shape specification of optical surfaces

Ferreira González, Chelo

; López García, José Luis

; Navarro, Rafael; Pérez Sinusía, Ester

(Optical Society of America, 2016) Artículo / Artikulua

A rigorous and powerful theoretical framework is proposed to obtain systems of orthogonal functions (or shape modes) to represent optical surfaces. The method is general so it can be applied to different initial shapes and ...

Orthogonal basis with a conicoid first mode for shape specification of optical surfaces: reply

Ferreira González, Chelo

; López García, José Luis

; Navarro, Rafael; Pérez Sinusía, Ester

(Optical Society of America, 2016) Artículo / Artikulua

We present some comments to the paper 'Orthogonal basis with a conicoid first mode for shape specification of optical surfaces: comment'.

Zernike-like systems in polygons and polygonal facets

Ferreira González, Chelo

; López García, José Luis

; Navarro, Rafael; Pérez Sinusía, Ester

(Optical Society of America, 2015) Artículo / Artikulua

Zernike polynomials are commonly used to represent the wavefront phase on circular optical apertures, since they form a complete and orthonormal basis on the unit disk. In [Diaz et all, 2014] we introduced a new Zernike ...
