Abstract
Modern research devices allow obtaining a large amount of information in remote laser sensing of atmospheric aerosols. However, the increase in the data volume processed by the Fredholm integral equation of the first kind increases the processing time non-linearly. The paper describes a method using known algorithms for integral equation processing with the data of aerosols laser sensing. The use of several samples from the transmission spectrum at more than 1000 wavelengths makes it possible to determine the dispersed particles sizes in a short time with an acceptable error. The developed algorithm is approved for determining the granulometric composition of laboratory heterogeneous systems. The results of laser diagnostics and the particle sizes determined from the electron microscope images were compared.
