SUMMARY:Multi-color Holograms Improve Brightness in Holographic Displays
DESCRIPTION:Technical Communications, Technical Papers\n\nKoray Kavaklı (K
 oç University), Liang Shi (Massachusetts Institute of Technology), Hakan U
 rey (Koç University), Wojciech Matusik (Massachusetts Institute of Technol
 ogy), and Kaan Akşit (University College London (UCL))\n\nHolographic disp
 lays generate Three-Dimensional (3D) images by displaying single-color hol
 ograms time-sequentially, each lit by a single-color light source. However
 , representing each color one by one limits brightness in holographic disp
 lays.\n\nThis paper introduces a new driving scheme for realizing brighter
  images in holographic displays. Unlike the conventional driving scheme, o
 ur method utilizes three light sources to illuminate each displayed hologr
 am simultaneously at various intensity levels. In this way, our method rec
 onstructs a multiplanar three-dimensional target scene using consecutive m
 ulti-color holograms and persistence of vision. We co-optimize multi-color
  holograms and required intensity levels from each light source using a gr
 adient descent-based optimizer with a combination of application-specific 
 loss terms. We experimentally demonstrate that our method can increase the
  intensity levels in holographic displays up to three times, reaching a br
 oader range and unlocking new potentials for perceptual realism in hologra
 phic displays.\n\nRegistration Category: Full Access\n\nSession Chair: Yif
