Paper Abstract

The finite element analysis of mirrors is now common practice. The results of such an analysis is the vector displacement of a great number of grid points within the mirror. Evaluation and interpretation of the raw data is difficult, even when represented as contour plots. It is more convenient from an optical engineer's viewpoint to describe the total deformation in terms of its components: tilt, defocus, and common aberrations. A NASTRAN post-processing program is described which performs a least squares fit of Zernike polynomials to a deformed surface.
