Paper Abstract

The goal is to develop and demonstrate the potential benefits of applying the controlled structures technology (CST) approach to active and adaptive optics. The potential advantages were outlined in a previous paper. Two testbeds are envisioned for the experimental work. CST techniques are demonstrated experimentally on the first, a simple deformable mirror testbed (DMT) incorporating piezoelectric sensors and actuators and a single optical displacement sensor. Implementation of passive damping augmentation, local control and global high authority control is demonstrated. Some of the key issues in the approach to the control of larger interferometers or lightweight Cassegrain telescopes are discussed. Finally, some of the open areas for future research are summarized.
