Claim Text:
1. A method of forming an aspheric mirror, comprising: manufacturing a mirror segment having a substantially spherical surface contour; attaching actuator assemblies at a plurality of contact points along an outer edge of the mirror segment, wherein an actuator assembly includes a first pair of actuators for controlling a radial force and a tangential moment on the mirror segment at the contact point and a second pair of actuators for controlling an axial force and a radial moment on the mirror segment at the contact point; and activating the actuator assemblies to apply a load to deform the mirror segment to a substantially aspheric surface contour, wherein the mirror segment includes a central hole that defines an inner edge of the mirror segment, further comprising attaching actuator assemblies at each of a plurality of contact points along the inner edge of the mirror segment and activating the actuator assemblies along the inner edge of the mirror segment.
