Диагностика примесей в каплях жидкостей с использованием оптических методов

Abstract

The results of experimental studies on determining the effect of solid particles in water aerosol droplets on the interference pattern of the latter are presented. A pulsed Nd: YAG laser and a CCD video camera were used to create an interference pattern. The radii of water aerosol droplets were 10-140 µm. We used four types of solid particles with a mass concentration of 0.003-1 g/l. Specific types of interference patterns due to the presence of impurities in the droplet are identified. The effect of the type and concentration of impurities on the integral characteristics of interference patterns (number and type) has been established. We have proposed an approach for determining the concentration and size of impurity particles based on the analysis of interference patterns.
