Nanotechnology Researchers Are One Step Closer to the Perfect ‘Meta-lens’ for AR/VR Headsets
While 1mm thick meta-lenses capable of bending incoming light to a singular focal point have been previously demonstrated, the researchers say they’ve refined their design, allowing for arbitrarily adjustments to the transmission speed of light passing through different points on the lens. By modulating the transmission speed, the light can be made to arrive simultaneously at the focal point, resulting in a sharper image, the researchers say.
Once designed, meta-lenses can be created as part of a wider mass production process: for instance, of VR headsets or augmented reality glasses. They can also be used in place of more expensive ground-glass camera lenses on smartphones and laptops, reducing weight, thickness and cost of portable devices.
There’s no word yet on when the lens tech will be ready for production—or for what cost—but it’s possible that upgrades of this type could follow a similar path set out for future VR headset displays.
