59‐1: Enhancing Brightness with Multi‐Color Holography

Holographic displays traditionally project full‐colored holograms time‐sequentially to achieve colored images. Time‐sequential image formation limits the achievable brightness levels. This work introduces a new method to achieve brighter images in holographic displays. Unlike the usual approach, our method allows three light sources to simultaneously illuminate the displayed holograms at different intensity levels. We optimize phase holograms along with the required intensity levels for each frame using our gradient‐descent based optimization pipeline.
