Abstract

Optical turbulence causes fluctuations in the refractive index along a propagation path, leading to severe distortions in laser beams, which in turn cause a reduced performance of electro-optical systems like directed energy weapons, imaging systems, and free space optical communication systems. We propose experimental characterization of the optical turbulence height profile in the maritime and littoral surface layer, leveraging the versatility and mobility of Unmanned Aerial Vehicles (UAVs) over a vertical path. Initial experiments include a stationary set up to measure laser beam intensity fluctuations at five points along a vertical down link of ~30 m length. Our research results have applications for optical communication and energy delivery system between airborne and surfaced platforms (submarine or ship) through the marine surface layer.
