Paper Abstract

The U.S. Naval Observatory (USNO) is in the design and very early construction phases of a project to construct and operate an optical interferometer dedicated to astrometry. An overall description of the instrument is given with emphasis on those features which make the device uniquely suited for astrometric observations of the type envisioned. A brief discussion of these types of observations is included. A few of the more general considerations in the design and operation of the instrument are also mentioned. This instrument is in many ways an extension and an enlargement of the MARK III Interferometer at Mt. Wilson which has successfully made astrometric measurements.
