Abstract | Holographic displays have recently shown remarkable progress in the research field. However, images reconstructed from existing display systems using phase-only spatial light modulators (SLMs) are with noticeable speckles and low contrast due to the non-Trivial diffraction efficiency loss. In this work, we investigate a novel holographic display architecture that uses two phase-only SLMs to enable high-quality, contrast-enhanced dis-play experiences. Our system builds on emerging camera-in-The-loop optimization techniques that capture both diffracted and undiffracted light on the image plane with a camera and use this to update the hologram patterns on the SLMs in an iterative fashion. Our experimental results demonstrate that the proposed display architecture can deliver higher-contrast and holographic images with little speckle without the need for extra optical filtering. |
