SUMMARY:Large Étendue 3D Holographic Display with Content-adaptive Dynamic
  Fourier Modulation

 n\nEmerging holographic display technology offers unique capabilities for 
 next-generation virtual reality systems. Current holographic near-eye disp
 lays, however, only support a small etendue, which results in a direct tra
 deoff between achievable field of view and eyebox size. Etendue expansion 
 has recently been explored, but existing approaches are either fundamental
 ly limited in the image quality that can be achieved or they require extre
 mely high-speed spatial light modulators. We describe a new etendue expans
 ion approach that combines multiple coherent sources with content-adaptive
  amplitude modulation of the hologram spectrum in the Fourier plane. To ge
 nerate time-multiplexed phase and amplitude patterns for our spatial light
  modulators, we devise a pupil-aware gradient-descent-based computer-gener
 ated holography algorithm that is supervised by a large-baseline target li
 ght field. Compared with relevant baseline approaches, ours demonstrates s
 ignificant improvements in image quality and etendue in simulation and wit
 h an experimental holographic display prototype.\n\nRegistration Category:
