Paper Abstract

The ongoing progress of shape-controlled mirrors for enabling lower mass, large segmented mirrors is described in the context of Raytheon's AMSD Program. This approach has been successfully applied in the past for room temperature telescopes as large as 4-meters in aperture (at 70 kg/m2) and for cryogenic mirrors as large as 3-meters in aperture (at 30 kg/m2). The AMSD Program is producing similar mirror segments at 15 kg/m2 while simultaneously investigating advanced manufacturing techniques with the potential for significant reductions in cost and schedule for multiple segments of a large aperture.
