A deployable, annular, 30m telescope, space-based observatory

Architecture for in-space robotic assembly of a modular space telescope

“…There exist many proposed concepts for future space telescopes larger than the JWST, including three configurations from the Advanced Technology Large-Aperture Space Telescope (ATLAST) study ranging from 8 to 16 m, 3 the 11.7-m HDST, 2 annular 20 to 30 m telescopes using a bicycle wheel structure, 12,13 and the Membrane Optical Imager for Realtime Exploitation (MOIRE) 20-m telescope that uses membrane diffractive optics.…”

Advanced Imaging Methods Using Coded Aperture Digital Holography

“…[58]. Another application is imaging using telescopes with an annular aperture, which is a way to reduce the weight of space-based telescopes [59]. The images produced by such telescopes might be clearer and sharper using COACH [60].…”

Hexapod for Space Telescopes: A Review

“…Mirror fabrication and polishing costs are reduced by eliminating much of the total mirror area. Furthermore, silicon carbide (SiC) is a material used for mirror because of its light weight that also reduces the costs of launch [2]. Due to Zerodur mirrors bend under radiation a full SiC (Silicone Carbide) telescope is preferred to alternate Zerodur mirror [3].…”
