    Resonance light scattering as a means for ultrahigh resolution sizing of liquid droplets in the 5 to 50 µm diameter range is reviewed. So far, the technique has been used to make relative size measurements with resolutions of 30 ppm on individual, nonevaporating droplets and 300 ppm on individual, evaporating droplets. The calculated existence of resonances sharper than those observed thus far offers the possibility of size resolutions approaching 0.1 ppm on highly transparent spherical droplets. The paper also reviews the relatively small amount of reported work on resonance light scattering from aerosols and from individual aspheres.
