Compact design for optical-see-through holographic displays employing holographic optical elements
Optics Express, 2018 Holographic AR display is a promising technology for head-mounted display devices. However, it usually has a complicated optical system and a large form factor, preventing it from widespread applications. In this work, we propose a flat-panel design to produce a compact holographic AR display, where traditional optical elements are replaced by two ...

Responsive Materials, EarlyView.We reported a stress‐guided photo‐programming strategy that enables cholesteric liquid crystal elastomers (CLCEs) to achieve synchronous 3D shape morphing and structural color evolution from a single 2D film. Abstract Flexible materials with dynamic structural colors have attracted considerable interest for multilevel information interaction, showing ...

Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions
Small, EarlyView.By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

Small Methods, EarlyView.The 3D beating dynamics of eukaryotic flagella drive motility, sensory functions, and resource acquisition, yet highly non‐planar beating patterns remain poorly characterized. Based on Digital Holographic Microscopy, holoV3C enables label‐free 3D reconstruction of such complex dynamics with 53 nm axial resolution, demonstrated on mouse sperm and ...
