Polarization holography for the detection and Poincaré sphere mapping of vector vortex beams

Our report details a novel approach using polarization holography for the precise detection of vector vortex beams' (VVBs) polarization distribution. We will discuss multiple methodologies facilitated by this technique, offering insights into VVBs' characterization. Upon successful detection, we extract the VVBs' polarization states, allowing for their accurate placement on the Poincaré sphere. The obtained results affirm polarization holography's potential as an effective alternative to conventional measurement methods. This advancement propels polarization holography towards widespread adoption in optical component processing.
