ABSTRACT
A laser heterodyne receiver of scattered light was used to detect dust grains vibrations. We made experiments for estimation of the technique sensitivity. The vibrations were excited in cigarette smoke with a loudspeaker. The results obtained indicate that dust grains vibrations with amplitude of about 30 nm can be detected.
