We now consider beam propagation through atmospheric turbulence using the paraxial form of the extended Huygens–Fresnel principle [23]: (5)E(ρ,z,w)=-ikexp(ikz)2πz∬E(r,w)×exp[ik(ρ-r)22z]exp[ψ(ρ,r,z)]d2r, where r and ρ are position vectors in the source plane and rec...
The root-mean-square (rms) of the residual wavefront, after propagation through atmospheric turbulence and corrected from Zernike polynomials, has been derived for the von Kármán turbulence model. The rms for any location in the telescope pupil and the pupil average rms have been calculated. It...
After a 5.5 km propagation through atmospheric turbulence with Cn2=10-15m-2/3, the target OAM power proportion of the RAPVB and the APVBA could be maintained above 15 %, while the target OAM power proportion of the APVBA is 0.1511, which is slightly higher than the target OAM power ...

Of particular interest are the changes in waveform, peak pressure, and rise time of the model N waves after they have passed through the model turbulence. A review is first given of previous experiments on the effect of turbulence on both sonic booms and model N waves. This experiment was ...
We propose and demonstrate a single channel interferometer that can be used to study how vortex beams propagate through a scatterer. The interferometer consists of a multifunctional diffractive optical element (MDOE) synthesized by the spatial random multiplexing of a Fresnel zone plate and a spiral ...
The accuracy and reliability of the measured differential path in satellite synthetic aperture radar (SAR) interferometry are strongly affected by the uncertainty in the estimation of the atmospheric contribution. Changes in the physical parameters of the medium, due to turbulence layers or gas concentra...
