Orthogonal basis with a conicoid first mode for shape specification of optical surfaces
Chelo Ferreira, Jose L. Lopez, Rafael Navarro +1
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…
Orthogonal systems of Zernike type in polygons and polygonal facets
Chelo Ferreira, Jose L. Lopez, Rafael Navarro +1
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…
Olver's asymptotic method: a special case
Chelo Ferreira, Jose L. Lopez, Ester Perez Sinusia
We consider the asymptotic method designed by F. Olver [Olver, 1974] for linear differential equations of the second order containing a large (asymptotic) parameter : $x^my"-Λ^2…
Generalization of Zernike polynomials for regular portions of circles and ellipses
Rafael Navarro, José L. López, José A. Díaz +1
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…
