Scattering of laser radiation from condensed phase of heterogeneous smoky plasma

Abstract

A technique for research the spatial structures of the condensed phase grains in heterogeneous smoky plasma by determining the laser scattering indicatrix modulated with a frequency of 60 kHz in three spectral intervals was developed. An experimental stand was created to register the laser scattering indicatrix on the wavelengths of 808 nm, 630 nm and 532 nm in the scattering angles range from 0 to 170º with a measurement time of 3 seconds. A program of registration and processing of measurement results on a computer has been developed. Tests of the experimental complex on the flame of metalized fuel compositions were carried out.
