FIELD: physics, atomic power.
SUBSTANCE: invention relates to nuclear power engineering and can be used in making fuel elements for nuclear reactors. The method involves scanning the image of spherical particles with a circular optical spot and determining the area of projections thereof. The diameter of the spot is selected to be less than the lower bound of the range of diameters of the image of the particles. Regions where the area of intersection of the scanning spot with images of particles is equal to the area of the scanning spot are selected. The area of the projection of each particle is defined as the area of the circle whose diameter is equal to the sum of the diameter of the scanning spot and the diameter of the region selected in said particle.
EFFECT: elimination of the operator and automation of image processing.
