Paper Abstract

Next generation space telescopes with apertures >10m will require novel technologies to permit lightweight primaries to operate at the diffraction limit in the optical regime. One solution is to construct a telescope from a lightweight, membrane primary, which is holographically corrected for surface distortions, in situ. We have demonstrated the correction of >10,000 waves of error in a 1-m diameter primary having an areal mass of just 17 grams per square meter.
