An assembly suitable for restoring and retaining a desired curvature profile for an optical system. The optical system may comprise a base structure, and a plurality of displacement actuators for positioning at least one of a plurality of optical elements, for example, mirrors, to the base structure, so that the optical elements have a desired curvature profile. Arbitrary and deleterious inputs to the optical system, which may tend to misalign the optical elements, thereby vitiating the desired curvature profile, are sensed by the assembly. The assembly computes new displacement actuator commands, for restoring the desired curvature profile.
