zconic: Zernike coefficients for a conic surface

In mlpeck/zernike: Zernike Polynomials

Zernike coefficients for a conic surface

Description

Calculates the radially symmetric Zernike coefficient values up to order nmax for a conic surface relative to a sphere of the same paraxial radius of curvature.

Usage

zconic(D, rc, b = -1, lambda = 1e-06, nmax = 6)

Arguments

D	Diameter
rc	Radius of curvature
b	Conic constant
lambda	Wavelength – defaults to 632.8 (nm)
nmax	Maximum radial polynomial order. Defaults to 6.

Details

For the typical use case D and rc should be in millimeters and lambda in nanometers.

Value

A vector of length nmax/2-1 of coefficient values, in increasing radial order, n=c(4,6, ...).
