ZernikeWFE
(name='Zernike WFE', coefficients=None, radius=None, aperture_stop=False, **kwargs)[source]¶ Bases:
poppy.wfe.WavefrontError
Define an optical element in terms of its Zernike components by providing coefficients for each Zernike term contributing to the analytic optical element.
- coefficients : iterable of floats
- Specifies the coefficients for the Zernike terms, ordered according to the convention of Noll et al. JOSA 1976. The coefficient is in meters of optical path difference (not waves).
- radius : float
- Pupil radius, in meters, over which the Zernike terms should be
computed such that rho = 1 at r =
radius
.
