Abstract
It has been pointed out that the shape of indicatrix of scattering laser beam on dust particles, assumed to be spherical, depends on grain size. This results from the fact that the angel of scattering is proportional to changes in interfering potential The device based on the above assumption can be measure granularity of particles with diameters scattering light at angles limited by the discrimination of the system. The measurement results presented graphically are repeatable and comparable with results obtained by professional instruments. Sericite dusts were used for reference in the investigation to be compared with dusts from most common types of cargoes carried by ships of the Polish merchant fleet.
