Experimental verification of phase discontinuities induced scintillation enhancement under weak perturbations
Han-Tao Wang, Hua-Jun Zhang, Lu Zhang +3
We verify the existence of scintillation enhancement by measuring the scintillation index of a beam composed of two coherent Gaussian vortex beams with topological charges…

Measuring optical vortices by means of dual shearing-type Sagnac interferometers
Hantao Wang, Huajun Zhang, Mingyuan Ren +2
Measuring the positions of optical vortices is an essential part in the researches of speckles and adaptive optics. The measurement accuracy is restricted by the performance of opt…

Phase discontinuities induced scintillation enhancement: coherent vortex beams propagating through weak oceanic turbulence
Hantao Wang, Huajun Zhang, Mingyuan Ren +2
Under the impact of an infinitely extended edge phase dislocation, optical vortices (screw phase dislocations) induce scintillation enhancement. The scintillation index of a beam c…
