Dual-Path Holographic Laser-Excited Volumetric Display
This research introduces a novel dual-path holographic laser rendering system capable of generating centimeter-scale volumetric graphics directly in physical space. By employing two synchronized optical paths, each combining a femtosecond laser, liquid-crystal spatial light modulator (LCSLM), a 3D beam scanning module, and an Xe-filled rendering volume, the system achieves significantly improved brightness and voxel density. The prototype was successfully demonstrated at SIGGRAPH 2024, showcasing interactive volumetric graphics with sufficient brightness under normal room lighting, user safety, and intuitive interaction. Key contributions include the development of a dual-path rendering method for centimeter-scale, high-density graphics, achieving high visibility under ambient light by selecting an optimal gaseous medium (Xenon), and integrating safety and interaction features into a robust prototype. This work represents a significant stride towards practical laser-excited volumetric displays that can naturally coexist with users in physical environments.
