    Fourier transform heterodyne spectroscopy: a simple novel technique with ultrahigh (150 mHz) resolution, at EICOLS '87 Conference (Åre, Sweden), Monday, June 1, 1987
    Light beating spectroscopy has been used from the early days of the laser to study light scattering. By detecting the beating signal between the scattered light and a 'local oscillator' field derived from the same laser, resolving powers of 10^14 have been achieved. The Fourier transform heterodyne spectroscopy presented here is simpler and more direct than the conventional heterodyne techniques using autocorrelators or spectrum analyzers.
