Abstract

This paper proposes an ultra-lightweight design of space reflectors made of polymer thin layers, to increase the aperture size of space observation platform with higher imaging resolution. The morphing capabilities are evaluated with both petal-like segmented and monolithic configured reflectors as the primary mirror of space telescopes, by forming a set of Zernike modes. Finally, a compound control strategy using a deformable relay mirror to compensate the residual surface error corrected partially by the active unimorph primary mirror.
