Abstract

Standard transmissometer techniques for measuring beam attenuation are unable to distinguish unperturbed, transmitted light from light scattered in the forward direction. Recent research efforts have proposed methods to distinguish forward-scattered photons by exploiting the spatial incoherence caused by scattering. We revisit the approach of Alley et al. (2018) and further explore the changes to coherence structure caused by particle scattering. We consider methods to decrease the data processing time, motivated by the goal of an in-situ sensor that can be evaluated in real time. Additionally, we consider how experimental devices could be optimized to perform in high-noise, marine environments.
