Abstract

Two high-speed, multi-actuator deformable mirrors have been characterized in terms of their abilities to provide low order Zernike mode shapes. Both mirrors are piezoelectrically activated with one having 61 actuators in a concentric circular array and the other having 52 actuators in a cornertruncated square array. Tilt, focus and astigmatism modes have been imposed with good linearity and fidelity. Superposition of multiple modes has also been successfully demonstrated. Problems encountered are listed.
