Paper Abstract

Achieving optimal performance from a multiple element telescope is critically dependent on an element position sensing and control system. We first discuss the design of a novel absolute distance measuring interferometer with performance suitable for such a sensing system, and secondly describe how it can be simply integrated into the telescope. Features of the interferometer include an extended ambiguity range, high temporal bandwidth, and very high accuracy. The concept for the overall optical alignment system is expected to compensate in part for local atmospheric distortions as well as mechanical vibrations while not interfering with the optical performance of the telescope.
