Abstract:

We analyze the errors in a Zernike-polynomial description of the deformation over a noncircularly symmetric portion of the overall input pupil of an optical system. Analysis reveals that Zernike polynomials can be used for such description, provided certain restrictions are observed. In this paper, we describe an example where Zernike polynomials are used to describe and assess the adverse effect of primary-mirror deformation on image quality in a three-mirror off-axis anastigmat.
