Ocular Capillary Ischemia Offers Early Warning of Diabetic Eye Disease Progression
An AI-driven automated optical coherence tomography angiography (OCTA) review system predicted progression of diabetic macular ischemia (DMI) with greater than 90% accuracy, a retrospective cohort study showed. DMI of the superficial capillary plexus at baseline more than doubled the risk of progression of diabetic retinopathy (DR), and DMI of the deep capillary plexus more than […]
Compact amplifier could revolutionize optical communication
Researchers at Chalmers University of Technology, Sweden, present a unique optical amplifier that is expected to revolutionise both space and fiber communication. The new amplifier offers high performance, is compact enough to integrate into a chip just millimeters in size, and — crucially — does not generate excess noise. “This could be compared to switching […]
Reconfigurable metasurfaces provide nanoscale light control: Technique inspired by the art of paper cutting used to make metasurfaces that could benefit optical displays and information encoding
Researchers have designed electromechanically reconfigurable ultrathin optical elements that can be controlled and programmed on a pixel-by-pixel level. These versatile metasurfaces could offer a new chip-based way to achieve nanoscale control of light, which could lead to better optical displays, information encoding and digital light processing. “Metasurfaces are ultrathin and compact optical elements that can […]
