Paper Abstract

Next generation optical space telescopes with apertures > 10 m for imaging, lidar, communications and directed energy focusing will be unable to use conventional technologies which are impractical or too costly. Our resolution is to construct a telescope from a lightweight, membrane primary, which is holographically corrected for surface distortions, in situ. In order to design a practical space telescope, a scheme by which temporal variations in the mirror surface, caused by thermal and gravitational stresses must be found. We present evidence that a primary static hologram combined with a secondary adaptive optics system may be the least expensive and simplest approach.
