ASSEMBLY FOR STATIC AND DYNAMIC POSITIONAL CONTROL OF AN OPTICAL ELEMENT

An assembly suitable for statically and dynamically controlling an optical element, for example, a secondary mirror. The assembly realizes a novel design technique which treats the problems of static and dynamic control of the optical element, as subsumed moments of one interdependent problem. The one interdependent problem may be solved by way of a single structural design, featuring a unique lever arm, which can provide overlapping functions responsive, at one and the same time, to both moments.
