Dual-color dynamic holographic display referenced RGB optimization and system compactification.

In this Letter, we propose what we believe to be a novel method for compact color dynamic holographic displays by integrating hologram design with optimized RGB (red, green, and blue) component control. This approach simplifies the system layout and reduces performance requirements through weight optimization, enabling high-speed, high-quality holography without complex time/space multiplexing. Our key innovation lies in the joint optimization of hologram computation and color channel weighting, which reduces the hardware complexity of the spatial light modulator (SLM) display system while maintaining color performance. Numerical simulations and optical experiments validate the method's effectiveness, demonstrating a least half reduction in SLM complexity compared to conventional designs. The current implementation demonstrates a dual-color system, with full-color capability under active development.
