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…
Oceanic non-Kolmogorov optical turbulence and spherical wave propagation
Jinren Yao, Hantao Wang, Huajun Zhang +4
Light propagation in turbulent media is conventionally studied with the help of the spatio-temporal power spectra of the refractive index fluctuations. In particular, for natural w…
Outer scale of the wide-range Prandtl/Schmidt number spectrum on beam wander for oceanic optical turbulence
Jian-Dong Cai, Jin-Ren Yao, Han-Tao Wang +3
Light propagation in ocean is influenced by the refractive-index which is related to temperature, salinity, outer-scale, etc. Based on Hill's model 1 (H1), two kinds of oceanic ref…
Evolution properties of coherent Gaussian vortex beams propagating through weak oceanic turbulence and its application for measurement
Hantao Wang, Huajun Zhang, Mingyuan Ren +2
The cross-spectral density of coherent Gaussian vortex beams propagating through weak oceanic turbulence is derived from extended Huygens-Fresnel principle and Nikishov spectrum. T…
Wide-range Prandtl/Schmidt number power spectrum of optical turbulence and its application to oceanic light propagation
Jin-Ren Yao, Hua-Jun Zhang, Ruo-Nan Wang +3
Light influenced by the turbulent ocean can be fully characterized with the help of the power spectrum of the water's refractive index fluctuations, resulting from the combined eff…
