Shaping fractional orbital angular momentum beams through highly scattering media.

Fractional orbital angular momentum (FOAM) beams possessing radially notched intensity distributions play a unique role in fields such as optical manipulation and optical communication. Due to multiple scattering, the direct transmission of FOAM beams through highly scattering media, such as thick biological tissues and fog, remains challenging, inhibiting the applications of FOAM beams behind these media. To address this issue, we propose an approach to overcome high scattering and establish FOAM beams through highly scattering media.

Construction of vector vortex beams on hybrid-order Poincaré sphere through highly scattering media.

Vector vortex beams (VVBs) have attracted extensive attention due to their unique properties and their wide applications in fields such as optical manipulation and optical imaging. However, the wavefronts of the vector vortex beams are highly scrambled when they encounter highly scattering media (HSM), such as thick biological tissues, which greatly prevents the applications of VVBs behind HSM. To address this issue, we propose a scheme to construct VVBs of freewill position on the surface of hybrid-order Poincaré sphere (HyOPS) through HSM.
