Abstract
An experimental setup has been developed that allows recording the flux of probing radiation scattered from dispersed particles in the 0 degrees direction. To suppress the beam passing through the swarm of dispersed particles a reference beam was used.
The reference beam was formed from the probe beam and aligned in the registration plane with the beam passing through the swarm of particles. The Michelson interferometer was tested in an experimental setup to determine the sizes of dust particles of heterogeneous systems.
It was shown that by placing a heterogeneous system in one of the arms of the interferometer, it was possible to register the scattered radiation at the angle 0 degrees. This facilitates calculation of the sizes of particles with the same accuracy over the entire size range.
To verify the method the iron powder particles sized 50-63 mu m were used.
