Abstract

The design of a proposed 1-m diameter deformable secondary mirror is described, with emphasis on optimization of each component for adaptive optical correction. Finite element analyses are presented which investigate the ability of the mirror to match low-order Zernike polynomials. Wavefront data from a 1-m telescope are used to examine the ability of the mirror to fit atmospherically distorted wavefronts. Finally, mirror surface FEA results from the atmospheric wavefronts are Fourier transformed to predict pre- and post-correction image quality.
