SUMMARY:Large Étendue 3D Holographic Display with Content-adaptive Dynamic
  Fourier Modulation
DESCRIPTION:Brian Chao, Manu Gopakumar, and Suyeon Choi (Stanford Universi
 ty); Jonghyun Kim (NVIDIA); Liang Shi (Massachusetts Institute of Technolo
 gy (MIT)); and Gordon Wetzstein (Stanford University)\n\nEmerging holograp
 hic display technology offers unique capabilities for next-generation virt
 ual reality systems. Current holographic near-eye displays, however, only 
 support a small etendue, which results in a direct tradeoff between achiev
 able field of view and eyebox size. Etendue expansion has recently been ex
 plored, but existing approaches are either fundamentally limited in the im
 age quality that can be achieved or they require extremely high-speed spat
 ial light modulators. We describe a new etendue expansion approach that co
 mbines multiple coherent sources with content-adaptive amplitude modulatio
 n of the hologram spectrum in the Fourier plane. To generate time-multiple
 xed phase and amplitude patterns for our spatial light modulators, we devi
 se a pupil-aware gradient-descent-based computer-generated holography algo
 rithm that is supervised by a large-baseline target light field. Compared 
 with relevant baseline approaches, ours demonstrates significant improveme
 nts in image quality and etendue in simulation and with an experimental ho
 lographic display prototype.\n\nRegistration Category: Full Access, Full A
