Abstract
The results of a number of research projects related to the phasing of segmented telescope primaries are presented. The behavior of a segmented mirror controlled using edge position sensors is examined using the results of a numerical simulation. The performance of a novel approach to the optical sensing of piston differences is analyzed. The effect of segmented manufacturing errors on both the phasing control system and telescope performances is discussed. Finally, a concept for an `autonomous segment mirror' is presented and its feasibility assessed.
