The additional degrees of freedom that arise from segmenting the optical surfaces naturally allow for the development of active control of orbital thermal fluctuations and mechanical stresses as well as atmospheric compensation. The successful performance of segmented optical systems depends on ability to position and control the segments. We briefly review the goal of segment control and our exact analytical solution to adaptive optics segmented mirror control(superscript 1). Our completely deterministic control solution eliminates the need to do iterations and eliminates the need to develop iterative control algorithms. We also present diffractive concepts for segment position metrology that exploit and transfer diffractive measurement technology from crystallography and condensed matter physics.
