In men's singles, India's top three - Kidambi Srikanth, Lakshya Sen, HS Prannoy - are all placed in the same half.

Researchers have come up with a new technology to deliver augmented and virtual reality glasses that don’t look like “bug eyes.” “Image” is everything in the $20 billion market for AR/VR glasses. Consumers are looking for glasses that are compact and easy to wear, delivering high-quality imagery with socially acceptable optics. In a new paper in Science Advances, researchers describe imprinting freeform optics with a nanophotonic optical element called “a metasurface.” The metasurface is a veritable forest of tiny, silver, nanoscale structures on a thin metallic film that confo...

Metaform optics point to compact AR/VR glasses and imaging components 05 May 2021 University of Rochester combines metasurfaces and freeform optics for compact high-resolution systems. Years in the making: metaform components New optical systems of the kinds required for augmented and virtual reality (AR and VR) displays are likely to exploit developments in novel components such as metasurfaces and freeform optics, and the non-classical optical behavior that they can provide. Customizable optics using these components in small form-factor platforms is also attractive for several high-resol...

University of Rochester “Image” is everything in the $20 billion market for AR/VR glasses. Consumers are looking for glasses that are compact and easy to wear, delivering high-quality imagery with socially acceptable optics that don’t look like “bug eyes.” University of Rochester researchers at the Institute of Optics have come up with a novel technology to deliver those attributes with maximum effect. In a paper in Science Advances, they describe imprinting freeform optics with a nanophotonic optical element called “a metasurface.” The metasurface is a veritable forest of tiny,...

Rare barnacle goose spotted in Abbey Wood's Crossness Nature Reserve. Photo - Terence Baker A rare type of goose, once thought to be a fish, has been spotted at a nature reserve in Abbey Wood. The barnacle goose were once believe to have hatched from barnacles in the sea, spawning a 1000-year old myth. These days, the creatures exist in tiny numbers in the UK, with just a breeding population of 900 feral pairs, and they have amber UK conservation status. Three barnacle geese have been photographed at Crossness Nature Reserve in Abbey Wood, the site of one of the last remaining areas o...
