Abstract
In light scattering methods of measuring particles, in which photocounters or photometers are used to measure the light scattering phenomena in the particles, and the sizes or the concentrations of the particles are discovered, the measurement characteristics are affected to a considerable degree by the optical characteristics of the particles, that is, by their refractive index. The effects of this light absorption rate of the particles on the light scattering measuring characteristics of particles were considered by means of clarifying theoretically the complex number refractive index dependency of the light scattering characteristics of the particles, which forms the basis for this influence. The results are reported.
