We have developed a Fourier analysis technique for resolving close binary stars with the Fine Guidance Sensor system of the Hubble Space Telescope. Transfer mode scans are segmented into the individual passes and autocorrelated, and then a summed autocorrelation is formed for each observation. High resolution information is then obtained by Fourier deconvolution using a single star template autocorrelation. The method is described and preliminary results are presented for certain known spectroscopic binaries. Potential limitations of the method are also discussed.

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 NAS 5-26555. These observations are associated with proposal # 9034.
