ABSTRACT

The article deals with the method of measurement of size and number of disperse particles for technological purposes, for the estimation of quality and efficiency of technological processes. Some space filled with dispersed particles is probed by beam of low-power laser radiation. Simultaneously with probing laser radiation, dispersed particles are exposed to ultrasonic excitation. Oscillating dispersed particles may be assumed as scatterers with dynamically changing shape of surface. Intensity of light, scattered at these particles, is time-dependent as well. Using dynamic component of radiation, scattered and reflected from dispersed particles, natural frequencies of mechanical oscillations and particle sizes are defined.

Key words: disperse particle, optiko-acoustic method, probing radiation, ultrasonic, natural frequencies.
