What is the ultimate VR/AR displays? Holographic near-eye displays promise to deliver full 3D experience and have made remarkable progress over the last few years. Unlike conventional displays, holographic displays are based on phase only spatial light modulators (SLMs) and can show 3D images by shaping a wave field such that the target image is created through interference. However, holographic displays had suffered from poor image quality because of the wrongly optimized phase patterns, imperfect SLM, mismatch between ideal wave propagation and real world, etc. In this presentation, we will introduce recent research efforts from Nvidia and Stanford researchers to solve the above problems. For example, the optimized phase pattern calculated in real-time with a learned wave propagation model (Neural Holography), speckle reduction with a partially coherent light source (Speckle-free Holography), or higher contrast with another SLM and camera-in-the-loop optimization (Michelson Holography).
