In this paper, we introduce a simplified technique for the generation of vector beams employing polarization holograms recorded on azo-functionalized copolymer film. The method involves recording two holograms sequentially on the same area of the sample using an interferometer setup. After recording, simply illuminating the hologram with a Gaussian beam from a laser produces a vector beam. By rotating the polarization state of the reading beam, different vector beams on the higher-order Poincare sphere (HOPS) can be generated. This technique is simple, compact, and scalable and holds promising potential in optical information processing applications.
