Abstract
The determination algorithm of aerosol microparticles' size distribution by iteration process is described. In the described method the particle, registered by optoelectronic devices is characterized by parameters of amplitude and duration of impulse. Distribution of particles' size is determined from the measured functional dependence of number of registered particles from amplitude and duration of the proper electric impulses on the output photo-detector. Given dependence, within limits of statistical errors, is repeated when performing measurement series in the medium with identical optical parameters. It is linked by functional dependence to relative particles' fraction of different sizes, which is expressed by integral first kind Fredholm equation.
