Characterization of turbulence effects in perfect optical vortex via holographic techniques

The experimental generation and characterization of a perfect optical vortex under the effect of simulated atmospheric turbulence are presented in this work with the aid of holographic techniques. Computer-generated holograms and spatial light modulators have been used to optically generate perfect optical vortices with integer and fractional orbital angular momentum. Moreover, using the technique of digital holographic interferometry, these perfect optical vortices were analyzed. From a single setup, it was demonstrated how this vortex under the effect of turbulence propagates along the <i>z</i> axis, the transverse intensity profiles, and the phase map. The results of this work provide information for the improvement of the correction of aberrant beams and images by means of adaptive optics for optical communications and imaging. Furthermore, we present an experimental perspective to investigate the propagation of optical beams and vortex in free space under turbulence effects by means of the technique of digital holography. The use of the holographic technique is an investigative approach to the optical disturbance in a beam propagating through atmospheric turbulence, which can be extended to several optical vortices (OVs) using the same experimental setup.
