    Freeform Optics and Metasurfaces Create Compact AR/VR Eyewear

    Article obtained from Photonics RSS Feed.

    A team from the University of Rochester’s Institute of Optics imprinted freeform optics with a metasurface, in a combination of optical technologies that charts a course for a new fabrication method for AR/VR glasses. The metasurface, a silver nanoscale structure on a thin metallic film, conformed to the freeform shape of the optics used in the work, which allowed the researchers to develop an optical component that they call a “metaform.”

    The metaform defies the conventional laws of reflection, gathering the visible light rays entering an AR/VR eyepiece from all directions and redirecting them directly into the human eye.

    “Metasurfaces are also called ‘flat optics,’ so writing metasurfaces…
