Paper Abstract

We present a data fitting method that uses the near orthogonality of the Circular Zernike Polynomials 41(r,9) on the data collected on an interferogram in order to obtain the best rms fit. This is obtained through the generation of an orthogonal basis from the 4(r,9) on the discrete and irregular interferometric data set give by the experimental circular pupil. The rms fit with this basis is comparable to analogous methods to a fraction of computational time, cost and requirements.
