Loss of radio frequency modulation on optical carrier in high scattering medium: effects of multiple scattering and field of view selection

Abstract

We show the effect of multiple scattering on the shape of the pulse returned by a modulated lidar for bathymetry studies. Multiple scattering lengthens the tracks of individual photons, and consequently broadens pulse shape destroying the modulation. However, the reduction of the detector field of view allowed us to sharpen the pulses and to restore the modulated signal.
