Paper Abstract

A wide variety of deformable mirror structures have been studied for wavefront correction since the advent of adaptive optics nearly two decades ago. These structures generally fall into two categories: 1) segmented facesheet and 2) continuous facesheet. In addition there are two methods of correction: 1) zonal control and 2) modal control. The basic mirror types are discussed and analyzed in terms of wavefront correction capabilities. Curve fitting characteristics are explained in terms of the optical influence function and mirror meshing functions. Basic design equations and finite element models are developed for the overall system including mirror component parts such as actuators, facesheet, basal structure, and electronic drivers.
