Active Mirror Structures

Abstract

This report summarizes work done on a Large Active Mirror Structure Design at the University of Arizona. The design goal is a 4 meter diameter aperture, f/1.5 primary mirror. The recommended mirror structure uses a 2 cm by 4 m diameter solid ULE faceplate supported on a low bandwidth active truss support structure whose principal backplate component is made of high stiffness graphite epoxy material. Loads are distributed between the mirror component and the backplate such as to introduce corrections for errors due to mechanical and thermal distortion. This report carries through a detailed structural analysis and provides recommendations for implementation of an extremely lightweight mirror appropriate for either space or terrestrial use.
