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.
Vector vortex beams (VVBs) have attracted world’s attention due to its promise of unprecedented capabilities for applications. It is important that develop an easy and feasible method to character the spatially inhomogeneous distribution of polarization of VVB. In this paper, we propose a method for measuring the polarization distribution of arbitrary vector vortex beams using polarization holography. The experimental results show that the results measured by polarization holography for VVBs are basically similar to those measured by the conventional method. We believe that polarization holography is expected to become a popular optical component processing technology in future.
