A classical limitation of stellar interferometry techniques at optical wavelengths is the difficulty of generating true images. This arises from atmospheric effects which destroy the phase relationship between the varied spatial frequency components of the object. The problem has been solved in recent observations of the spectroscopic binary Capella with the two-telescope interferometer at CERGA. As described by Koechlin (1977) the technique utilizes the distortion of the interference fringes observed in dispersed light. As a result, the 180 deg ambiguity herebefore associated with the position angle of Capella is now removed, giving the true orientation of the orbit. The technique appears applicable to more complicated stellar morphologies. Traditional interferometric observations with the same instrument and a computerized method of analysis yield relative positions of the components for several orientations with a 4 milli arc-second accuracy in the E-W direction and 0.4 milli arc-second in the N-S direction.
