Segmented active / adaptive thin shell mirrors
Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation VICurrent ELTs use comparatively thick segmented mirrors with a support structure / warping structure of significant mass. In this publication we present a method to develop Segmented Thin Shell Mirrors that are intended to be supported by multiple actuators mounted on a backing structure.

Co-focus control of segmented primary mirror telescopes based on segmented mirror pose detection
Applied OpticsA method for the co-focus closed-loop control of segmented primary mirrors in astronomical telescopes is proposed based on pose detection. The pose changes of each segment relative to a reference segment are calculated by constructing a pose estimation matrix.
