Abstract

A mixed numerical and analytical technique is presented to investigate OAM beam scattering in turbid water. Single particle scattering from an OAM beam in an underwater environment is computed numerically using COMSOL Multiphysics Modeling Software to generate single scattering functions. The array theorem extends this single scattering function to multiple scatters in a three dimensional space. Simulations predict that OAM illumination reduces forward scattering in low turbidity environments compared to scattering from Gaussian beams. In high turbidity water, scattering results from OAM beams and Gaussian beam converge. Experimental results are presented that are consistent with predictions from simulation.
