Optical systems may contain mechanical structure, optics, sensors, and active control to improve image quality or to point and stabilize the line-of-sight. A single model that includes structural, optical, and active control elements is beneficial for trade studies and defining hardware requirements. The process and benefits of representing structural and optical elements as a state space model are discussed. A state space model is derived for a reaction-less steering mirror. Steering mirror control and performance are discussed. A method for creating state space models directly from finite element normal modes is also described. A single closed loop model that represents both structural and optical effects in the state space form can be used to quickly evaluate system performance.
