Measurement of integral parameters in the investigations of optical properties of aerosols

Abstract

Due to the vast expansion of the range of research dealing with the particle sizing i.e. the number of specialists and institutions dealing with particle sizing as well as an increasing stream of measuring information, works dealing with elaboration of new measuring methods, where the problems of precise determination of a measured value are the most important in practice, have become of great importance. The presented way of optical properties of aerosols measurements, expressed by integral parameters such as ordinary moments of the particle size distribution function, is an example where on the expense of full information about the examined medium which is the knowledge of the function n(a), integral parameters have been used.

Many numerical problems resulting from the assumed model of scattering, have been avoided here |4|. This way of operation allows also for the elimination of errors resulting from the integral transformation. Presented way of the optical properties of aerosols measurements can be realized by means of a simple autonomous measuring device equipped with a small counting unit.
