Composite deformable mirror

Abstract

A mathematical model for a spherical hexagon mirror is described along with the model verifications. A flat hexagon epoxy mirror with aluminum core is used in test procedures in addition to a flat aluminum honeycomb mirror. Deformable reflector concepts are discussed and piezoelectric actuators are analyzed. The concept of a deformable mirror can be used to improve the overall RMS error of the mirror as presently designed and/or make necessary on-orbit adjustments.
