UCLA Breakthrough in 3D Imaging: 28 Layers, One Shot

Researchers at the UCLA Samueli School of Engineering have developed a novel light-programmed system capable of projecting high-resolution three-dimensional images across 28 depth layers simultaneously, marking a significant advance in holographic display technology. Published in Light: Science & Applications, the research introduces a hybrid digital-optical architecture that combines deep learning with diffractive optics to generate volumetric images in a single exposure.

The work was led by Prof Aydogan Ozcan of UCLA’s Electrical and Computer Engineering Department and the California NanoSystems Institute (CNSI).

Three-dimensional displays are increasingly important for applications ranging from holography and augmented reality (AR) to virtual reality (VR) and advanced visualisation systems. However, creating dense 3D images with multiple closely spaced depth planes remains a major challenge. As image layers move closer together, optical interference, known as crosstalk, reduces image quality and depth perception.
