Paper Abstract

The eccentric three-mirror telescope presently proposed for free space optical communications exhibits diffraction-limited image performance for a relatively large field of view, allowing the design of a simpler coarse-pointing mechanism and a wider range for a fine-pointing mechanism without associated losses of antenna gain. Light baffling in this telescope design is excellent, and allows a reduction of stray light to a minimum; its system parameters are less sensitive than those of two-mirror telescopes, allowing looser tolerances and simplifying structural design.
