Abstract:

This paper presents a new semi-empirical method of solving the inverse laser-probing problem for the particles of a polydisperse aerosol. Measuring the optical density of an air flow of aerosol particles at three wavelengths of the probe laser radiation made it possible to obtain the mean volume-surface size of the particles, which is associated by correlation dependences with the parameters of the scattering function of the particles over sizes. Good agreement is obtained with the data of direct measurements for the particles of a cement aerosol.

Keywords:
