Abstract

Single-mode fibers have been proposed for connecting telescopes to mixing stations in coherent telescope arrays intended for image synthesis. We describe a laser-controlled servosystem that keeps the fiber-optical length differences stable and permits passage of wide-bandwidth astronomical beams from an unlimited number of telescopes. Initial laboratory results are presented.
