FIELD: instrumentation.
SUBSTANCE: lighting of flux of particles with a light beam and recording of parameters of light signals shaped by particles at their flying through the pointed-out area of the particle flux is performed. After the flux passage using reflecting mirrors, the light beam is turned with regard to an initial beam and is again passed through the flux, where recording of an image of particles by means of a CCD matrix is performed from three uniform corners. The obtained images of particles are transmitted to a computer for digital processing. In order to get a final conclusion on the shape of a particle of a complex structure, coefficients of shapes for each of the projections are compared.
EFFECT: automation of an analysis process of particles of an arbitrary shape.
