Waveguide‐Based Retinal Projection Near‐Eye Display with Bidirectional Eyebox Expansion

open access: yesAdvanced Intelligent Systems
Based on the mechanism of human visual imaging, retinal projection display (RPD) directly projects images onto the retina, achieving sharp images without relying on the focal adjustment of human eye. However, the physiological phenomenon of eye movements

The Brain Response to Reflectional Symmetry Is Not Uniquely Preattentive

open access: yesEuropean Journal of Neuroscience, Volume 64, Issue 1, July 2026.
An example of a ‘glass pattern’ used in the current study. The current study investigates brain responses to this type of Regularity across three different tasks and compares it to the brain response to reflectional symmetry patterns. ABSTRACT EEG can be used to measure the brain response to visual regularity.

Dynamic Holographic Display With Multiplexed Dielectric Metasurfaces

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Based on multiplexed metasurfaces, we show hybrid multiplexing of polarization, wavelength, and orbital angular momentum can be applied for dynamic tuning. Our strategy presents a highly compact and efficient solution for high‐capacity, multi‐dimensional holography, with promising applications in advanced displays, data storage, optical encryption, and
