Paper Abstract

The finite element method is used to perform optimization of an actively controlled mirror's structural design. The theory of the method of modeling actuators is developed followed by execution of a test case demonstrating the effectiveness of this method in improving the correctability of a lightweight mirror. Design variables include shape and sizing optimization of the mirror's structural design. The design objective is the root-mean-square optical surface error after best correction of a wavefront with power aberration. Design constraints are applied to the mirror weight and the mounted natural frequency.
