Abstract

As a beam of light propagates through the atmosphere, scattering by aerosol particles causes the beam profile to broaden. A multi-field-of-view (MFOV) lidar has been developed which makes simultaneous measurements of the energy directly backscattered from the central beam and multiscattered signals arising from the broadened part of the beam. The direct backscatter signal constitutes a conventional Mie lidar signal. Measurements made along a near horizontal path in haze, fog, and rain are presented. The results show that the multiscattered signals are strongly influenced by the extinction coefficient and the size of the aerosols. Thus the multiscattered signals, together with the direct backscatter signal, contain more information about the aerosols than is available from a conventional single field of view lidar.
