Abstract

Structured light can enhance the functionality of optical communication and sensing systems. Dense scattering environments such as those experienced in coastal water or foggy conditions result in degradation of structured optical fields. We present findings that indicate the preservation of phase structure of beams for Ballistic Light carrying Orbital Angular Momentum (OAM) propagated through a dense scattering over short (<3m) distance with attention of up to 20dB. We present a numerical channel modelling approach that can predict the scattering behaviour at extended distances, which indicate that there is a strong mode dependant variance in crosstalk from the interaction of beams that carry OAM with randomly displaced scattering particles. These result present an exciting possibility to use OAM modes as a long distance particulate sensor and could potentially lead to the development of novel tools for monitoring the particles in the environment.
