摘要：
We demonstrate that the technique of Stimulated Raman Scattering (SRS) is a practical method for the simultaneous characterization of diameter, number density and constituent material of microsize droplets. The method is applicable to all Raman active materials and to droplets with a diameter of at least 8 mu m. Our experimental study was focused on water and ethanol monodisperse droplets in the diameter range of 40-90 mu m. Results of a single laser pulse and multiple pulses are analyzed, indicating that the SRS method can diagnose droplets of mixed liquids and ensembles of polydisperse droplets.
