Theoretical and experimental research of light scattering on driven shape oscillations by liquid droplet levitated by ultrasound

Method of control of the particles' size by the measurement of light intensity scattered on a fixed particle at the first order rainbow angle has been developed. Object of research was the single droplet of benzol levitated in the water by ultrasound. It was demonstrated that the Airy's theory is applicable to particles of the size less than 500 μm. Modification of the method using the functional dependence of frequency of the self-resonant low loss spheroidal oscillations on droplet's size is considered. Possibility of determination of the surface tension of liquid droplet by light scattering at the first order rainbow angle is demonstrated. Resonant character of light scattering on spheroidal oscillations of droplet is used. Schematic diagram of the experimental apparatus including CCD-camera is described.
