Meter‑scale depth and multi‑polarization addressable zoom 3D metaholography

Author:

The Qiong-Hua Wang team at Beijing University of Aeronautics and Astronautics has proposed a meter‑scale, multi‑polarization‑addressable, zoomable three‑dimensional metahologram. By elucidating the polarization‑multiplexed three‑dimensional Fourier metaholographic diffraction principle, the authors’ designed metasurface not only overcomes the depth‑range limitations of conventional metaholography but also enables multi‑polarization control. By developing a specialized liquid material, they have introduced a large‑aperture, high‑focal‑length polarization‑tunable liquid lens with a 6‑mm aperture and integrated it into the metasurface. Furthermore, this polarization‑tunable liquid lens, based on the integration of a liquid‑crystal light valve, can simultaneously adjust both focal length and polarization state using a single driving voltage. The proposed metaholographic technique achieves multi‑polarization‑addressable three‑dimensional reconstruction, with a holographic image depth extending up to the meter scale—approximately 80 times greater than that of conventional Fourier metaholography. This meter‑scale, multi‑polarization‑addressable, zoomable three‑dimensional metahologram holds promise for meeting the broad application demands in fields such as encryption, optical data storage, and super‑resolution imaging.

The research findings were published in Nature Communications on September 16, 2026, under the title “Meter-depth and multi-polarization addressable zoom 3D meta-holography.”
