As a promising candidate for the next-generation mobile platform, mixed reality (MR) such as Apple Vision Pro and Meta Quest Pro (both are passthrough virtual reality headsets) has the potential to ...

Researchers at the University of California, Los Angeles (UCLA) have unveiled a new optical technology that enables precise focusing of light—only in one direction. This novel unidirectional focusing ...

Terahertz imaging exploits electromagnetic waves in the spectral region between microwaves and infrared (0.1–10 THz) to probe the internal structure and composition of a wide range of materials. It ...

Diffractive optics harness microscale surface relief patterns to sculpt optical wavefronts through diffraction, offering compact, lightweight alternatives to conventional refractive lenses. Recent ...

Fresnel zone plates (FZPs) are widely used for X-ray focusing and imaging thanks to their compactness and high resolution compared to refractive or mirror-based X-ray optics. However, achieving high ...

“Diffractive and refractive optical elements have become an integral part of most high-resolution X-ray microscopes. However, they suffer from inherent chromatic aberration. This has to date ...
