Paper Abstract

Interferometric measurements of real surfaces are combined with computed optical design analyses. To accomplish this, a special software interface driver was developed to accept serial Optical Path Difference (OPD) data from a Zygo Mark III interferometer, apply standard algorithms, and convert the measured data into a CODE V readable file. Analysis was conducted on a large aperture developmental optical system containing a fold mirror of eggcrate construction. MTF performance of the entire system was computed as were the contributions of individual surfaces to overall optical quality. Diffraction effects due to the rib structure of the eggcrate mirror were apparent in this analysis, as were the effects of gravity and figure components of the wavefront. This hybrid analysis demonstrates the usefulness of coupling interferometry with an optical design program in the analysis of complex optical systems.
