Abstract

We have studied theoretically the problem on the resonance excitation of surface oscillation of the transparent liquid weakly viscous particles of arbitrary size under the modulated laser irradiation. The dependence of the droplet surface deformation amplitude on the radiation modulation frequency was determined for different values of the particle radius. The characteristics of induced oscillation of particles at their resonance excitation were investigated. The increase of the resonance characteristic width of surface oscillation was observed with the particle size decrease and with growth of liquid viscosity as well. The problem of light scattering on oscillating liquid particles was numerically studied. The greatest modulation of scattered light is shown to occur in the directions normal to the incident radiation, as well as in the direction of primary rainbow.
