      Abstract: Polarization holography has important application prospects in the field of data storage and polarized light imaging due to its ability to record amplitude, phase and polarization information. In addition, it also has the ability to regulate light fields, which can regulate special light fields with helical phase distribution and spatial polarization distribution. Such special light fields have broad application prospects in the fields of optical communication, particle manipulation, photon entanglement, etc. There is also a lot of research focused on how to generate such beams. The latest research progress in preparing vector beams, scalar vortex beams, and vector vortex beams by using polarization holography is introduced in this paper. The light field regulation method based on polarization holography has the advantages of a simple fabrication process, the small size of the optical system and low production cost, which provides a new idea for the manufacture of special light fields.
