SUMMARY:Depolarized Holography with Polarization-multiplexing Metasurface
DESCRIPTION:Technical Papers\n\nSeung-Woo Nam, Youngjin Kim, Dongyeon Kim,
  and Yoonchan Jeong (Seoul National University)\n\nThe evolution of comput
 er-generated holography (CGH) algorithms has prompted significant improvem
 ents in the performances of holographic displays. Nonetheless, they start 
 to encounter a limited degree of freedom in CGH optimization and physical 
 constraints stemming from the coherent nature of holograms. To surpass the
  physical limitations, we consider polarization as a new degree of freedom
  by utilizing a novel optical platform called metasurface. Polarization-mu
 ltiplexing metasurfaces enable incoherent-like behavior in holographic dis
 plays due to the mutual incoherence of orthogonal polarization states. We 
 leverage this unique characteristic of a metasurface by integrating it int
 o a holographic display and exploiting polarization diversity to bring an 
 additional degree of freedom for CGH algorithms. To minimize the speckle n
 oise while maximizing the image quality, we devise a fully differentiable 
 optimization pipeline by taking into account the metasurface proxy model, 
 thereby jointly optimizing spatial light modulator phase patterns and geom
 etric parameters of metasurface nanostructures. We evaluate the metasurfac
 e-enabled depolarized holographic display through simulations and experime
 nts, demonstrating its ability to reduce speckle noise and enhance image q
 uality.\n\nRegistration Category: Full Access, Enhanced Access, Trade Exhi
