SUMMARY:Simultaneous Color Computer Generated Holography
DESCRIPTION:Eric Markley, Nathan Matsuda, Florian Schiffers, Oliver Coissa
 rt, and Grace Kuo (Meta)\n\nComputer generated holography has long been to
 uted as the future of augmented and virtual reality (AR/VR) displays, but 
 has yet to be realized in practice. Previous high-quality, color holograph
 ic displays have made either a 3x sacrifice on frame rate by using a seque
 ntial color illumination scheme or used more than one spatial light modula
 tor (SLM) and/or bulky, complex optical setups. The reduced frame rate of 
 sequential color introduces distracting judder and color fringing in the p
 resence of head motion while the form factor of current simultaneous color
  systems is incompatible with a head-mounted display. In this work, we pro
 pose a framework for simultaneous color holography that allows the use of 
 the full SLM frame rate while maintaining a compact and simple optical set
 up. Simultaneous color holograms are optimized through the use of a percep
 tual loss function, a physics-based neural network wavefront propagator, a
 nd a camera-calibrated forward model. We measurably improve hologram quali
 ty compared to other simultaneous color methods and move one step closer t
 o the realization of color holographic displays for AR/VR.\n\nRegistration
