Abstract
The modulation factor of intensity-modulated radiation scattered by aerosol particles is investigated. It is shown that if the optical fields scattered by individual particles interfere at the photodetector, the modulation of the received signal will be preserved. It is shown experimentally that the modulation factor of the scattered radiation decreases with increasing diameter of the receiving aperture.
