Scientific paper

Since 1996, a team at the University of Arizona has been designing and fabricating lightweight, active space mirrors. These glass/composite mirrors use a thin flexible substrate for the optical surface and an actuated composite structure for support. We present a design method that yields the best figure correction for the lightest mass by assuming that the substrate's material properties are the limiting parameters. The results are such that the designer decides on a total mass budget and an aperture area, and the algorithm provides the substrate thickness, number of support points, and the mass distribution between the substrate and actuators.
