Abstract

A new optical technique for determining the evaporation and condensation rate of flowing liquid droplets is described. The same technique can also be used to detect small shape distortions. The method is based on the precise measurement of resonance peaks in the fluorescence spectrum. These resonances, which are a sensitive function of the size, shape, and index of refraction of dye-impregnated dielectric micro-objects, have been called morphology-dependent resonances.
