Structured optical fields have interesting interactions with free-space channels due to their continuously evolving environmental conditions. We will discuss our recent work on modelling, mitigation and measurement of changes in weather conditions with twisted light.
OAM beams are distorted by changes in weather as they propagate through air. We demonstrate an experimental measurement system that identifies weather conditions with 99.6% accuracy in 12 seconds, considerably faster than traditional scintillometer approaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
