Paper Abstract

Orthonormal polynomials have long been used to describe optic surface errors. Previously, the product of Fourier and Legendre polynomials has been used to describe the surface errors of grazing incidence optics. We have applied an alternative set, Fourier-Fourier polynomials, to describe the surface errors. This set functionally differs from the Fourier-Legendre set in that each term has a finite bandwidth frequency spectrum. We discuss the advantages of this difference with respect to predictions of grazing incidence telescope performance based upon measured surface figure errors.
