SUMMARY:Multi-color Holograms Improve Brightness in Holographic Displays
DESCRIPTION:Technical Papers\n\nKoray Kavaklı (Koç University), Liang Shi 
 (Massachusetts Institute of Technology), Hakan Urey (Koç University), Wojc
 iech Matusik (Massachusetts Institute of Technology), and Kaan Akşit (Univ
 ersity College London (UCL))\n\nHolographic displays generate Three-Dimens
 ional (3D) images by displaying single-color holograms time-sequentially, 
 each lit by a single-color light source. However, representing each color 
 one by one limits brightness in holographic displays.\n\nThis paper introd
 uces a new driving scheme for realizing brighter images in holographic dis
 plays. Unlike the conventional driving scheme, our method utilizes three l
 ight sources to illuminate each displayed hologram simultaneously at vario
 us intensity levels. In this way, our method reconstructs a multiplanar th
 ree-dimensional target scene using consecutive multi-color holograms and p
 ersistence of vision. We co-optimize multi-color holograms and required in
 tensity levels from each light source using a gradient descent-based optim
 izer with a combination of application-specific loss terms. We experimenta
 lly demonstrate that our method can increase the intensity levels in holog
 raphic displays up to three times, reaching a broader range and unlocking 
 new potentials for perceptual realism in holographic displays.\n\nRegistra
