Abstract

The development of the optimum locations of actuators for an adaptive optic has in the past been a manually iterative process. Such a manual process becomes fruitless when multiple disturbance cases (e.g., gravity and thermoelastic deformations) need to be considered in the development of a single actuator layout. A more automated yet efficient method is desired to quickly develop an optimum actuator layout and the associated optical performance. A genetic design optimization algorithm is developed and implemented in software. The method is then demonstrated on an example adaptive optic design to show how it can be used to develop optimum actuator layouts for a fixed number of actuators or to conduct design trades in choosing the number of actuators.
