Abstract: The HST Fine Guidance Sensors (FGS) will be characterized as science interferometers, with particular emphasis on the use of fringe scanning for binary star research. Issues of instrument calibration and stability will be discussed. The capabilities and limits of FGS as to magnitudes, magnitude differences, and angular separations of binary components will be demonstrated, and recent results on specific binaries will be presented. This work is based on observations made with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555.
