Structured light signal transmission through clouds

Dynamic media such as atmospheric clouds and fog form a formidable barrier to light propagation for free-space optical communication (FSO). To overcome an obstacle, we propose make use of the acoustic properties laser filament coupled together with donut-shaped signal beam. A generated by ultrafast is accompanied wave that clears cylindrical chamber around filament’s plasma column can mimic transmission channel. We present method couple Laguerre–Gauss beam through obstacle-free image measure transmitted carried structured demonstrate efficient FSO cloudy conditions, which requires low energy, resilient noise, unaffected filament.
