Abstract

The design of a space-based interferometer with a large number of apertures has been a subject of much discussion. In this paper, we argue in favor of using a Michelson beam combiner for the case where a small field of view is acceptable. We address the normal criticism that a Michelson combiner is too complicated by presenting an optical design for a 90-aperture, laboratory prototype. Coupling this device to a large, ground-based telescope with a coherent fiber array forms an imaging system that is a significant improvement over aperture masking.
