Abstract
An assembly that can provide corrections of distortions of a mirror. The assembly uses the method of active optics to apply forces to the mirror to introduce deformations that cancel out the distortions. An important feature of the assembly is the employment of a force actuator which comprises a closed feedback loop that closes around the force actuator. An advantage of this novel feature is that, in response to a disturbance to the force actuator, the feedback loop can maintain a desired controlled force for application to the mirror.
