Abstract

A scalable wavefront correction device with high spatial and temporal frequency is described in terms of the concept and technologies developed for its realization. Electronic microcircuit technology is combined with traditional wavefront corrector methods to define the proposed integrated wavefront corrector (IWC) concept. The development of unique point-of-departure actuator material allows large electrostrains to be generated at reduced applied voltages. The specifications of the device are given and the detailed structure is shown in drawings. The single-layer actuator technology can be fabricated at a density of about 500 actuators per square cm. The composite structure developed for this adaptive optics technology is shown to preserve the structural integrity required for phase compensation, and provide the packing density requirements of high spatial frequency. The device is shown to permit large-scale wavefront correction and is of interest to deformable mirror technology.
