Paper Abstract

Optical surface deformations are spline fitted using several algorithms including that from the ACCOS V optical analysis program (Scientific Calculations, Inc., Fishers, New York). The effects of spline fitting errors are investigated. The effect on image quality of deformation of the primary mirror in the Solar Optical Telescope (SOT) must be investigated. NASA's NASTRAN finite element thermal-mechanical structural analysis program is used to simulate the deformations due to various types of thermal and mechanical loading. Several simulated NASTRAN outputs are used to generate a deformed surface for spline fitting. The ACCOS V spline fitting algorithm is compared to other spline fitting alogrithms. The effects on the optical analysis of spline fitting errors are presented.
