Experimental investigation on propagation characteristics of vortex beams in underwater turbulence with different salinity
-
Abstract: We build a device which can control both the salinity and the intensity of underwater turbulence to study the propagation characteristics of vortex beams and a Gaussian beam in underwater turbulence. In addition, we set up another experimental device which can transmit a longer distance, and studied the scintillation characteristics of the vortex beam with topological charge m=2 and a Gaussian beam over a propagation distance of 20 meters.
