Deep Neural Networks informed by wave optics generate full-color 3D holographic display without needing pre-computed label holograms

"only final intensity or amplitude of target scene is known, not the crucial wavefront phase, so large datasets pre-computed holograms as labels unobtainable... also, trade-off between reconstruction quality/ computational speed... overcome by learning mapping between target scene/ its hologram... lightweight multi-wavelength network creates realistic depth perception by computationally simulating optical field... future: overcome full-color still needing 3 separate network models, which triples computational resources"
