Paper Abstract

Advances in the fabrication of adaptive ceramic modules result in compact components that can be adapted to a variety of applications. The adaptive tertiary is a unique component that can provide a variety of functions. Individual modules integrated with a tip/tilt stage can provide auxiliary phasing control of future large segmented telescopes. In addition, each module can contain hundreds of individual actuators allowing the devices to also act as high-spatial frequency deformable mirrors. Measurements have shown that pathfinder devices can be assembled well within the capture range of the devices. This demonstrates the overall feasibility of the concept.
