SUMMARY:Wirtinger Holography for Near-eye Displays
DESCRIPTION:Technical Papers\n\nWirtinger Holography for Near-eye Displays
 \n\nChakravarthula, Peng, Kollin, Fuchs, Heide\n\nNear-eye displays using 
 holographic projection are emerging as an exciting display approach for vi
 rtual and augmented reality at high-resolution without complex optical set
 ups --- shifting optical complexity to computation. While precise phase mo
 dulation hardware is becoming available, phase retrieval algorithms are st
 ill in their infancy, and holographic display approaches resort to heurist
 ic encoding methods or iterative methods relying on various relaxations.\n
 \nIn this work, we depart from such existing approximations, and solve the
  phase retrieval problem directly revisiting complex Wirtinger derivatives
 . Using Wirtinger derivatives allow us to pose the phase retrieval problem
  as a quadratic problem which can be minimized with first-order optimizati
 on methods. The proposed Wirtinger Holography is flexible and facilitates 
 the use of different loss functions, including learned perceptual losses p
 arametrized by deep neural networks, as well as stochastic optimization me
 thods. We validate this framework by demonstrating holographic reconstruct
 ions with an order of magnitude lower error, in simulation and on a experi
 mental hardware prototype.\n\nRegistration Category: Platinum Pass, Full C
