zernike_slopes¶

mmtwfs.zernike.zernike_slopes(zv, rho, phi, norm=False)[source] [edit on github]¶

Calculate total slope of a set of Zernike modes on a polar coordinate grid, (rho, phi).

Parameters

zv: dict-like or ZernikeVector: ZernikeVector or dict-like with Zernikevector-compatible key naming scheme containing zernike polynomial coefficients.
rhondarray: Radial coordinate grid
phindarray: Azimuthal coordinate grid
normbool (default: True): Normalize modes to unit variance (i.e. Noll coefficients)

Returns

xslope, yslope: ndarray, ndarray: Total X and Y slopes of zv at each (rho, phi) point. Same shapes as rho and phi.
