    We propose a precise reconstruction, with crosstalk-free switching, of two holograms. Our approach utilizes orthogonal polarizations that illuminate the holograms to modulate both amplitude/phase and polarization, effectively mitigating crosstalk between the hologram data streams. Furthermore, the incorporation of a 90° interference angle facilitates the recording multiple holograms. Experimental results have demonstrated the high-precision decoding of amplitude, phase, and polarization data for two reconstructed holograms. The integration of orthogonally polarized light with a 90° interference angle sets the stage for achieving multi-dimensional polarization modulation in systems with more than two channels.
