Large Depth‐of‐Field, Large Eyebox, and Wide Field‐of‐View Freeform‐Holographic Augmented Reality Near‐Eye Display

open access: yesAdvanced Science, EarlyView.
This study proposes an augmented reality (AR) near‐eye display system that simultaneously achieves a large depth‐of‐field (DOF) from 0.25 to 10 m, a wide 50° field‐of‐view (FOV), and a 10 mm × 10 mm viewing eyebox, while maintaining high display performance, good optical see‐through viewing capability, and a compact system form factor.

Meta‐Dispersive 3D Chromatic Confocal Measurement

open access: yesAdvanced Science, EarlyView.
A dispersive metalens (DML) combined with the chromatic confocal method is achieved for high‐precision 3D measurement in this study. This approach enables both high axial and lateral resolutions in compact optics. The development offers a promising route toward precise, miniaturized depth sensing for future applications in microstructure inspection and

Magnetically Compensated Nanometer‐Thin Ga‐Substituted Yttrium Iron Garnet (Ga:YIG) Films with Robust Perpendicular Magnetic Anisotropy

open access: yesAdvanced Electronic Materials, EarlyView.
This study reports on the remanent magnetization 4πMr and the temperature dependence of the net magnetization of magnetically compensated Ga:YIG films. For samples with very low net magnetic moments, the compensation points Tcomp and the Curie temperatures TC are determined. Ga:YIG films exhibit a significant increase in effective magnetization 4πMeff,
