138 WFS Series
Note: The WFS software uses a slightly different numbering of the frequency
column. See the following table which is fully conform to the WFS software
definitions:
In contrast to the table from Malacara positive and negative frequencies are
switched in sign to get a more natural order.
Normalization factor
A normalization factor ‘Norm’ is used to convert the orthogonal set of Zernike
polynomials into a set of orthonormal functions having a 'Unity Variance' which
means that each normalized function has become a RMS variation of 1.
That is, the total measured wavefront variation for a particular mode is:
WFS_Coefficient * Norm_Factor * Zernike function.
