    MilliHertz Surface Spectroscopy, at Ninth International Conference on Laser Spectroscopy (Bretton Woods, NH), Thursday, June 1, 1989
    A technique that has been repeatedly employed in high resolution light scattering experiments is that of light beating, or heterodyne, spectroscopy. By detecting the beating signal between the scattered light and a 'local oscillator' derived from the same laser source, one can obtain ultrahigh spectral resolution, independent of the random fluctuations of the light source. We reported earlier of a novel Fourier transform heterodyne spectroscopy (FTHS) technique with high resolution which is simpler and more direct than the conventional heterodyne technique; we have since improved our...
