FIELD: instrument engineering.
SUBSTANCE: invention refers to optical instrument engineering and helps to investigate microparticles motion. Instrument for recording of ferro-microparticles motion is mounted on board of space vehicle. Space vehicle should be in conditions of free running at stationary orbit. Transparent vacuum ampoule with ferro-macroparticles is switched on. The ampoule is located in optical resonant cavity of gaseous laser, for instance CO2-laser with "blind" deflectors. From the outside the ampoule is equipped with electromagnetic system. The winding of the system is switched to either magnetising DC power supply or demagnetising AC power supply with exponentially falling amplitude. Radiation dispersed by ferro-microparticles is registered by low-noise photodetector.
EFFECT: record of micro-particles chaotic motion in vacuum in zero-gravity state.
