Paper Abstract

Using microelectronics, a 37-element hex pattern has been deposited on a thin PZT bimorph consisting of two wafers which produce changes in curvature with voltage applied to individual facets. The fabrication and optical performance of these devices are described, together with utilization schemes for atmospheric wavefront restoration based on rapid curvature sensing and correction.
