Abstract

A new method for dynamically deforming a thin mirror to correct the phase aberration function for defocus and astigmatism is presented. Three piezoelectric-type actuators, attached to the back edges and parallel to the front surface of the mirror, induce edge moments that bend the mirror to its desired shape for correction of the aberrated wavefront. A three-actuator deformable water-cooled mirror breadboard has been designed and built. Major features, design constraints, and performance expectations of the deformable mirror design are described.
