Model-Based Wavefront Sensorless Adaptive Optics System for Multi-Ring Perfect Optical Vortex Beams
In free-space optical communication (FSOC) applications, multi-ring perfect optical vortex beams (MR-POVBs) exhibit significant advantages owing to their high-dimensional multiplexing capacity and stable beam profile. However, during transmission, they are susceptible to atmospheric turbulence, which induces wavefront...
