On the possibility of coherent Doppler determination of the aerosol-size spectrum in a turbulent flow

The development of laser Doppler measurement of velocity (LDMV) raises the question of the possibility of working out new remote, contactless methods of determining the spectrum of aerosol particle sizes in a turbulent medium. The fact that particles of different sizes show differing lags in response to velocity pulsations of the medium [1] can be made the foundation of such methods.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Radiofizika, Vol. 21, No. 11, pp. 1703–1706, November, 1978.
