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

Thanks to a set of unique properties, diffractive optical elements have the potential to transform light into almost any desired distribution. Joshika Akhil gives the low-down on the technology that ...

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 ...

NASA has funded further development of a new type of solar sail relying on diffractive optics, with the ultimate aim of a demonstration mission in space. The “Diffractive Solar Sailing” project has ...

“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 ...
