The Dispersed Fourier Transform Spectrograph (dFTS) concept combines a Michelson interferometer with a dispersive spectrograph to provide high-resolution optical spectra of stellar targets. An internal laser metrology system calibrates the wavelength scale, yielding radial velocity accuracy as small as 1.5 m/s without a superposed reference spectrum. We deployed our second-generation instrument, dFTS2, to the Steward Observatory 2.3-meter Bok Telescope from June 2007 to June 2008, and undertook an observing program on spectroscopic binary stars, with the goal of constraining the velocity semi-amplitudes K1 and K2 of the binary orbits with unprecedented accuracy. We present orbital parameters for six spectroscopic binary systems and calculate stellar masses with relative uncertainties of 0.2% to 1.1%.
