SUMMARY:Tomographic Projector: Large Scale Volumetric Display with Uniform
  Viewing Experiences
DESCRIPTION:Technical Papers\n\nTomographic Projector: Large Scale Volumet
 ric Display with Uniform Viewing Experiences\n\nJo, Lee, Yoo, Choi, Kim...
 \n\nOver the past century, as display evolved, people have demanded more r
 ealistic and immersive experiences in theaters. Here, we present a tomogra
 phic projector for a volumetric display system that accommodates large aud
 iences while providing a uniform experience. The tomographic projector com
 bines high-speed digital micromirror and three spatial light modulators to
  refresh projection images at 7200 Hz. With synchronization of the tomogra
 phic projector and wearable focus-tunable eyepieces, the presented system 
 can reconstruct 60 focal planes for volumetric representation right in fro
 nt of audiences. We demonstrate proof of concept of the proposed system by
  implementing a miniaturized theater environment. Experimentally, we show 
 that this system has wide expressible depth range with focus cues from 25 
 cm to optical infinity with sufficient tolerance while preserving high res
 olution and contrast. We also confirm that the proposed system provides un
 iform experience in a wide range of viewing zone through simulation and ex
 periment. Additionally, the tomographic projector has capability to equali
 ze vergence state that varies in conventional stereoscopic 3D theater acco
 rding to viewing position as well as interpupillary distance. This study i
 s concluded with thorough discussion about tomographic projectors in terms
  of challenges and research issues.\n\nRegistration Category: Platinum Pas
