Light-programmed system projects 28-layer 3D images in single shot
Researchers at UCLA have developed a system that projects 28 distinct layers of 3D images in a single shot using a combination of a digital encoder and a passive diffractive optical decoder optimized through deep learning. The technology enables high-fidelity volumetric displays by encoding multiple images into a single phase pattern and using structurally optimized surfaces to route light to specific depths, reducing interference between layers. This advancement addresses a key challenge in 3D display technology by improving depth selectivity and image clarity, offering potential improvements for holography, AR/VR, and other immersive visualization applications. Experimental results confirmed the system's effectiveness, demonstrating accurate image projection and validating the feasibility of the hybrid digital-optical approach.
